What are weed fertilizers?
Weed fertilizers are essential nutrients added to the soil or irrigation water to ensure healthy and productive growth of cannabis plants. These fertilizers provide the necessary elements such as nitrogen (N), phosphorus (P), and potassium (K), along with other micronutrients, which are vital for development at each stage of cultivation. Using specific fertilizers for cannabis can significantly improve the yield, quality, and taste of the buds.
Types of cannabis fertilizers by cultivation phases
The cultivation of cannabis is divided into several phases, each requiring a specific type of fertilizer to maximize growth and production. Here we detail the appropriate fertilizers for each stage of the cannabis life cycle:
Germination and seedlings
In the germination phase and the beginning of the seedling stage, the nutritional needs are minimal. It is recommended to use mycorrhizae to accelerate root development and mild, well-balanced fertilizers with low N-P-K content, specifically designed for young plants. Liquid fertilizers are ideal at this stage because they are easily absorbed and avoid the risk of burning delicate roots. Additionally, it is crucial to ensure an adequate source of micronutrients to strengthen the root system.
Weed growth fertilizer
During the vegetative growth phase, weed plants require higher amounts of nitrogen (N) to promote vigorous development of stems and leaves. Growth fertilizers should have an N-P-K ratio where nitrogen is the predominant component. An example formula could be 3-1-2 or 4-2-3. These nutrients promote a robust and healthy structure, preparing the plant for successful flowering.
Pre-flowering and flowering
The transition from the vegetative phase to flowering, known as pre-flowering, requires an adjustment in feeding. During pre-flowering, phosphorus (P) and potassium (K) are gradually increased to stimulate the formation of buds and flowers. Once in the flowering phase, flowering fertilizers for cannabis should have a higher proportion of phosphorus and potassium (such as a 1-3-2 or 2-4-4 formula), which is essential for the development of large and dense flowers.
PK fertilizers and bud fatteners
PK fertilizers, rich in phosphorus and potassium, are fundamental in the final phase of flowering. These fertilizers are designed to "fatten" the buds, increasing their size, density, and resin production. A good PK fertilizer could have a formula of 0-10-10, 0-13-14, 0-50-30, or similar. These bud fatteners not only contribute to the weight and volume of the flowers but also improve the production of terpenes and cannabinoids, enhancing the aroma and effects of the weed.
Bud maturation and flavor
In the maturation phase, it is vital to gradually reduce the amount of fertilizers to allow the plants to consume the remaining nutrients. This helps to clean any residue in the buds, improving the final flavor. Many growers opt to use "flushing" products in the last weeks, which eliminate excess salts and improve the purity and taste of the final product.
Stimulants and additives for weed cultivation
To get the maximum yield from your cannabis plants, it is essential to complement basic fertilizers with specific stimulants and additives. These products enhance various aspects of plant growth and development, optimizing nutrient absorption and boosting flower and resin production.
Root stimulator
The root stimulator is a crucial additive in the early stages of cannabis cultivation. Its main function is to promote strong and extensive root development, which is fundamental for efficient nutrient and water absorption. Root stimulators usually contain natural hormones, vitamins, and algae extracts, which encourage rapid and healthy root system growth. This not only improves the plants' resistance to stress and diseases but also establishes a solid foundation for vigorous growth during the vegetative and flowering stages.
Growth stimulator
The growth stimulator is used during the vegetative phase to accelerate plant development. These products are formulated with a combination of growth hormones, amino acids, and micronutrients that favor greater chlorophyll production, improving photosynthesis and energy production. The result is faster and more robust growth, with plants developing more branches and leaves, better preparing them for abundant flowering. Growth stimulators can also help plants recover more quickly from stress situations, such as transplanting or adverse environmental conditions.
Flowering stimulator
The flowering stimulator is essential to maximize the productive potential of cannabis plants during the flowering phase. These additives contain a mix of phosphorus, potassium, sugars, and other components that promote the formation and fattening of buds. Additionally, many flowering stimulators include ingredients that increase resin and terpene production, improving both the yield and final quality of the harvest. By using a good flowering stimulator, growers can expect larger, denser, and more aromatic flowers, with a higher cannabinoid content.
Types of weed fertilizers
Success in cannabis cultivation largely depends on the choice of the right fertilizers. At Pevgrow, we offer a variety of options that cater to different cultivation needs and preferences. Below, we explain the characteristics and benefits of organic fertilizers, mineral fertilizers, and biominerals, so you can choose the one that best suits your cultivation.
Organic fertilizers for weed
Organic fertilizers are a popular choice among cannabis growers seeking more natural and eco-friendly cultivation methods. These fertilizers are derived from organic materials such as compost, manure, guano, bone meal, and plant and algae extracts. The benefits of organic fertilizers include:
- Soil improvement: They enrich the soil structure, increasing its capacity to retain water and nutrients.
- Slow nutrient release: They provide gradual and consistent feeding, avoiding the risk of overfeeding and root burn.
- Sustainability: They are biodegradable and environmentally friendly.
- Product quality: They can improve the taste, aroma, and overall quality of the buds.
Mineral fertilizers for cannabis
Mineral fertilizers, also known as chemical fertilizers, are formulated with mineral salts that dissolve easily in water, providing immediate nutrition to the plants. These fertilizers are ideal for growers seeking precise control over their plants' feeding and quick results. The main benefits of mineral fertilizers include:
- Immediate availability: Nutrients are immediately available to the plants, which is crucial during high-demand periods.
- Precision in dosing: They allow for exact adjustment of nutrient quantities according to the specific needs of the plants at each growth phase.
- High yield: They can significantly increase the yield and size of the buds due to the optimal availability of nutrients.
Biominerals, the middle ground
Biomineral fertilizers combine the best of both worlds: the naturalness of organics and the effectiveness of minerals. These products are formulated with a mix of organic and mineral nutrients, offering balanced nutrition that promotes both soil health and rapid, vigorous plant growth. The benefits of biomineral fertilizers include:
- Perfect balance: They offer both immediate and long-term nutrient release, ensuring continuous access to necessary nutrients for the plants.
- Soil improvement and yield: Like organics, they improve soil structure but also provide the rapid growth associated with minerals.
- Flexibility: They are suitable for a wide range of cultivation methods, including soil, coco, and hydroponics.
Formats of weed fertilizers
At Pevgrow, we understand that the choice of fertilizer format is crucial to meet the specific needs of your cultivation method and personal preferences. We offer a variety of formats so you can select the one that best suits your cannabis cultivation practices. Below, we present the main formats available:
Liquid fertilizers
Liquid fertilizers are a very popular choice among cannabis growers due to their ease of use and rapid absorption. These fertilizers dissolve easily in water, which facilitates their application both in irrigation and hydroponic systems. The benefits of liquid fertilizers include:
- Ease of application: They can be mixed directly with irrigation water, allowing for uniform nutrient distribution.
- Rapid absorption: Nutrients are quickly absorbed by the roots, providing immediate nutrition to the plants.
- Flexibility: They allow for precise control of dosing and can be easily adjusted according to the plant's needs at each cultivation phase.
Solid fertilizers
Solid fertilizers, also known as granulated or powdered fertilizers, are an excellent option for those who prefer a slower and more consistent nutrient release. These fertilizers can be mixed with the substrate before planting or applied as top-dressing during growth. Among the most well-known solid fertilizers are worm humus and bat guano, but you should know that there are many more. The benefits of solid fertilizers include:
- Prolonged release: They provide continuous nutrition to the plants, reducing the need for frequent applications.
- Soil improvement: They contribute to improving soil structure and fertility in the long term.
- Less frequent application: Ideal for growers who prefer less intervention and maintenance in their cultivation.
Tablets and pills
Fertilizer tablets and pills are a convenient and efficient solution for feeding cannabis plants. A while ago, only Bio-Tabs used this type of fertilizer, but today you have tablets from other brands like Advanced Nutrients, Top Crop, or B.A.C. among others. These concentrated forms of nutrients gradually dissolve in the substrate or irrigation water, providing controlled nutrient release. The benefits of tablets and pills include:
- Simplicity of use: Easy to apply, simply insert them into the substrate or dissolve them in water, reducing preparation time and effort.
- Controlled release: They provide gradual and consistent feeding, ensuring that plants receive balanced nutrition over a prolonged period.
- Space and storage: They take up less space and are easy to store, which is ideal for growers with space limitations.
Fertilizers for Cannabis According to the Type of Cultivation

How to Choose the Right Fertilizers for Weed
Choosing the right fertilizers for your weed grow is crucial to ensure a successful harvest. Here we explain the key factors to consider to make the best decision:
1. Grower's Personal Preferences
The choice of brand or type of fertilizer can be influenced by the grower's personal preferences. Some brands, like Advanced Nutrients, are popular for their advanced technology and ease of use, while BioBizz is preferred by those seeking organic and sustainable products. Research the available brands and choose one that aligns with your values and growing goals.
2. Growing Experience
The grower's experience is a crucial factor. Beginners can benefit from fertilizers that include automatic pH correctors, like the pH Perfect line from Advanced Nutrients, which simplify the feeding process. More experienced growers may prefer products that allow for more precise control, such as the three-part fertilizers (Grow, Micro, Bloom) from General Hydroponics.
3. Type of Grow
The type of grow (soil, coco, hydroponics, aeroponics) determines the type of fertilizer needed:
- Soil: Organic fertilizers like BioBizz Bio-Grow. If you want to prepare a rich and natural mix, don't miss this article explaining how to make Super Soil.
- Coco: Specific products like Canna Coco A and B.
- Hydroponics: Completely soluble solutions like Flora Series from General Hydroponics.
- Aeroponics: Nutrients that are quickly absorbed like Botanicare Pure Blend Pro.
4. Strains You Will Grow
Some cannabis strains have specific nutritional needs. Autoflowering strains, for example, require balanced and fast-absorbing fertilizers like Top Auto from Top Crop. If you want to expand your knowledge, here you can see the best specific fertilizers for autoflowering strains. Research the needs of the strains you plan to grow and select fertilizers that match those needs.
5. Available Budget
The budget can significantly influence the choice of fertilizers. High-quality organic products, like Advanced Nutrients, can be more expensive, but they offer long-term benefits in terms of flavor and sustainability. On the other hand, mineral fertilizers like Hesi or Atami offer good value for money and are effective.
6. Goals in Yield and Quality
If your main goal is to maximize yield and quality, consider fertilizers designed to increase flower and resin production. Bloombastic from Atami and Monster Bloom from Grotek are excellent options to improve the size and density of buds, as well as resin production. On the other hand, organic fertilizers from Biobizz and Canna offer better organoleptic properties of the final product, although the buds may be less tight or heavy compared to growing with mineral fertilizers.
EC and PH Table to Ensure Fertilizer Absorption for Weed
No matter the quantity and quality of the fertilizers you use to feed your cannabis plants if you don't adjust the PH so they can assimilate them. The EC or electrical conductivity is the ability to conduct electricity in an aqueous medium, and it can also be measured by the amount of dissolved salts, in this case in PPM (parts per million). Below you can see a table showing the optimal PH to achieve the best absorption of each of the macroelements and microelements that weed needs for its perfect development. At Pevgrow you will find PH meters and liquids to raise or lower the PH, as well as EC meters and dissolved salts meters.
Optimal PH by Element
Ideal PH Depending on the Week and Type of Cultivation
Ideal EC Depending on the Week and Type of Cultivation
PPM to EC Conversion
Cultivation Tables Depending on the Fertilizer Brand
Each brand of fertilizers for weed has its own cultivation table where they recommend the specific doses of each of their fertilizers depending on the week or cultivation phase the plants are in. In our blog we explain how to interpret these tables, and I advise you to take a look at them so you are clear on how to use these products:
- Advanced Nutrients Growing Table

Conclusion
Choosing the right fertilizers for your weed grow involves considering your personal preferences, level of experience, type of grow, strains, budget, and goals. Taking the time to research and select the products that best suit your needs will help you achieve a successful and high-quality harvest. Happy growing!
Frequently Asked Questions about Fertilizers for Weed
🚦What Fertilizer to Use for Cannabis?
The appropriate fertilizer depends on the growth phase and the medium used. For the growth phase, use a fertilizer rich in nitrogen and containing a good balance of other macro and micronutrients. In the flowering phase, opt for products rich in phosphorus and potassium with a lower proportion of nitrogen. For indoor cultivation, it is better to use liquid mineral fertilizers since small pots are usually used, but for outdoor cultivation, you can use natural solid fertilizers such as worm humus, bat and seabird guano, bone meal, manure, etc., and later apply liquid fertilizers for an extra boost.
On our blog, you can find articles related to worm humus or guano to expand your knowledge and learn how to use them effectively in your weed cultivation.
🌞How to Make Homemade Liquid Fertilizer for Weed Plants?
Making homemade fertilizers is an economical and sustainable way to nourish your plants. Here are some simple recipes:
- Banana Tea: Boil banana peels in water for 15 minutes, let cool, and strain the liquid. Rich in potassium, ideal for flowering.
- Coffee Grounds: Mix used coffee grounds with water and let sit for 24 hours. Strain and use for watering. Provides nitrogen.
- Nettle Tea: Soak fresh nettles in water for a week, strain, and dilute 1:10 before applying. Provides nitrogen and micronutrients.
If you want to expand your knowledge in this area, check out this article that explains how to make homemade fertilizers for weed.
🔍When to Fertilize Weed for the First Time?
Fertilize weed seedlings for the first time when they are between 2 and 3 weeks old, although this depends on the type of substrate you choose. With Light Mix, you can start from the second week, but with All Mix, you can wait up to 3 or even 4 weeks without needing to fertilize. It is important to start with a low dose (about a quarter of the recommended dose) and observe the plants' reaction before gradually increasing the amount of fertilizer.
📅How to Recognize and Treat Excess Fertilizer in Weed Plants?
Symptoms: Burnt leaf edges, yellow leaves, brown spots, and slowed growth.
Treatment: Perform a "flush" of the substrate with pH-balanced water (pH 6.0-6.5) to remove excess nutrients. Water abundantly until the water runs clear from the drainage. Then, reduce the fertilizer dose and adjust the feeding schedule.
To clear any doubts regarding excesses or deficiencies, I recommend reading these articles from our blog related to nutrient excess in weed cultivation:
🏆How Often to Fertilize Weed?
The frequency of fertilization varies according to the growth phase:
- Growth Phase: Fertilize once a week.
- Flowering Phase: Increase to twice a week.
It is crucial to follow the manufacturer's instructions and observe the plants' signals, adjusting the frequency and dose as needed to avoid overfeeding or deficiencies.
💧What is the Best Fertilizer for Weed?
There is no single "best" fertilizer, as it depends on various factors such as the type of cultivation (indoor, outdoor, hydroponics) and personal preferences. However, brands like Advanced Nutrients, BioBizz, and Canna are highly recommended for their effectiveness and quality. Advanced Nutrients is known for its pH Perfect technology, BioBizz for its organic products, and Canna for its formulations specific to each growth phase.
Although this is very relative and subjective, from the perspective of the writer, for germination, the best might be Seedbox from Plagron with its Seedbooster product, as a root stimulator, Advanced Nutrients with Voodoo Juice and the micro-life of Piranha and Tarantula, as base growth fertilizer, the best might be Bio Grow from Biobizz, the best base for flowering might be Bio Flores from Canna, for many people the best bud booster or PK is Monster Bloom from Grotek, as maturation accelerator, the best might be Ripen from GHE, to improve flavor, Flavor from Atami is a favorite, and as enzymes, the most effective might be Natural Power Enzymes Plus from Advanced Hydroponics of Holland. However, you should know that mixing products from different brands is not a good idea, and it is best to use the complete range of any of the well-known cannabis-specific brands, as they have all proven to work very well.
🧪How to Fertilize Weed?
To fertilize weed, follow these steps:
- Read the Instructions: Each fertilizer has its own usage instructions.
- Prepare the Nutrient Solution: Mix the fertilizer with water according to the recommended doses.
- Adjust the pH: The pH is regulated after adding all the products to the water, as some can alter this parameter.
- Water Your Plants: Ensure the substrate is slightly dry before applying the nutrient solution.
- Observe and Adjust: Monitor the plants for signs of nutrient deficiency or excess and adjust the doses as needed.
🏞️How Much Fertilizer Does Weed Need?
The amount of fertilizer weed needs varies depending on the product and the growth phase. Generally, it is better to under-fertilize than over-fertilize, as it is much easier to correct a deficiency than an excess. It is essential to follow the manufacturer's recommendations and start with low doses, gradually increasing according to the plants' response.
🎲What Fertilizer for Outdoor Weed?
