Sensi Cal-Mag Xtra Advanced Nutrients – Premium Calcium-Magnesium Supplement for Cannabis

Sensi Cal-Mag Xtra from Advanced Nutrients is your definitive solution to the frustrating puzzle of nutrient deficiencies, delivering a powerhouse blend of chelated minerals and organic kelp to restore your plants to vibrant health.

Ever stared at your plants, seeing yellowing leaves or rusty spots, and felt that sinking feeling of not knowing exactly what's wrong? You're not alone. Nutrient lockout and deficiencies can steal your harvest's potential, leaving you with weak plants and disappointing yields. It's a race against time to diagnose the issue before your crop suffers. But what if you didn't have to be a plant doctor? What if you could tackle the most common deficiencies—calcium, magnesium, iron—with one simple, powerful solution?

Sensi Cal-Mag Xtra is that solution. It's the most comprehensive Cal-Mag biostimulant engineered specifically for cannabis, not generic vegetables. While other supplements offer basic elements, Sensi Cal-Mag Xtra goes further. It features chelated calcium and magnesium for superior absorption, multiple forms of chelated iron to prevent binding in media like coco coir, and a rich dose of kelp packed with vitamins, amino acids, and trace minerals. This unique formula doesn't just patch up problems; it creates optimal conditions for robust growth, stronger cell walls, and enhanced nutrient uptake, turning your garden back into a sea of lush green.

Transform Your Grow with Targeted Nutrition

Forget generic supplements that leave you guessing. Sensi Cal-Mag Xtra acts like a multivitamin for your plants, addressing the specific nutritional gaps that hold cannabis back. It's the difference between struggling with pale, curled leaves and cultivating resilient, photosynthetically efficient plants that can support heavy, resinous buds. This product integrates seamlessly into any feeding regimen, whether you're in hydroponic systems, coco, or living soil, providing the foundational support your plants crave during both vegetative and flowering stages.

How to Use Sensi Cal-Mag Xtra for Maximum Results

Using this supplement is straightforward, but following these steps ensures you get the most out of every milliliter.

1. Shake Well: Always shake the bottle vigorously before use. This ensures the concentrated components are properly mixed for a balanced application.
2. Diagnose & Dose: For acute deficiency correction, use 2 ml per liter of water. Apply this solution directly to the root zone. Repeat after one week if symptoms persist.
3. Incorporate into Regular Feeding: For preventative maintenance and optimal plant health, add 1-2 ml per liter to your regular nutrient solution throughout the grow cycle.
4. Check pH: While designed to be compatible, always check your final nutrient solution's pH after mixing. It should be within the ideal range for your growing medium.
5. Observe and Adjust: Watch for signs of recovery—new growth should be healthy and green. Reduce to a maintenance dose once deficiencies are corrected.
6. Avoid Overuse: More is not better. Stick to the recommended dosage to prevent nutrient burn or imbalance.
7. Store Properly: Keep the bottle in a cool, dark place to preserve the integrity of the organic components.

Key Advantages and Benefits of Sensi Cal-Mag Xtra

• Chelated Mineral Complex: The advanced chelation process ensures calcium, magnesium, and iron remain highly available to plant roots, even in challenging pH conditions, leading to immediate and efficient uptake.
• Iron-Clad Defense for Coco: Its specially formulated chelated iron resists binding in cation-rich media like coco coir, preventing one of the most common deficiencies in soilless grows and ensuring your plants get this critical micronutrient.
• Kelp Power Boost: The inclusion of kelp provides a natural cocktail of vitamins, amino acids, and plant growth hormones, which stimulates root development, improves stress resistance, and enhances overall plant vigor and health.
• Complete Micronutrient Support: Beyond the main players, it supplies chelated manganese and zinc, crucial for enzyme function and robust flowering, preventing hidden deficiencies that can limit yield and potency.
• OMRI-Listed for Organics: Certified for organic cultivation, it allows you to correct deficiencies without compromising your organic growing principles or introducing synthetic chemicals.
• Universal Compatibility: It works flawlessly with all base nutrients and supplements, including Advanced Nutrients' pH Perfect® line and competitors' products, making it a versatile tool in any grower's arsenal.
• Saves Time and Guesswork: Instead of diagnosing between calcium, magnesium, or iron shortages, this one-bottle solution covers all bases, saving you hours of research and potential misdiagnosis.
• Promotes Stronger Plant Structure: Adequate calcium is essential for building strong cell walls, which translates to sturdier stems that can support larger buds and improved resistance to pests and diseases.

Care and Storage

Frequently Asked Questions

Can I use Sensi Cal-Mag Xtra in organic soil?

Absolutely. Its OMRI-listed certification means it's approved for organic cultivation. It integrates perfectly into organic soil and living soil systems, providing readily available minerals that microbes can further break down for your plants.

How often should I use it?

For deficiency correction, apply at 2 ml/L with a watering, and re-evaluate in one week. For maintenance, incorporate 1-2 ml/L into your regular feeding schedule from veg through early bloom. Always observe your plants' response.

Is it safe for seedlings and clones?

Yes, but at a reduced strength. Start with a quarter to half dose (0.5-1 ml/L) for young, sensitive plants to provide gentle support without overwhelming them.

Does it affect the pH of my nutrient solution?

Sensi Cal-Mag Xtra is designed to be pH-stable. However, it's always good practice to check and adjust the pH of your final mix after adding all components, especially when using it with non-pH-buffered base nutrients.

What's the difference between this and a regular Cal-Mag product?

Most Cal-Mag products are designed for general horticulture. Sensi Cal-Mag Xtra is formulated specifically for cannabis, with added kelp, a broader spectrum of chelated micronutrients (like manganese and zinc), and iron that resists lockout in coco—features most generic products lack.

Personal Experience of Pevgrow’s CEO (Alan)

Let me be straight with you: for years, I treated Cal-Mag as a simple 'insurance policy'—something to add if I saw problems. Sensi Cal-Mag Xtra changed that mindset completely. Now, it's a staple in my reservoir from week two of veg onward, especially in my coco runs. The difference is night and day. Before, I'd occasionally get those tell-tale rust spots or interveinal chlorosis on fast-growing sativas, and I'd be scrambling. Now, those issues simply don't appear. The plants just look... healthier and more robust. The inclusion of kelp is a game-changer; you can see it in the root mass and the overall stress tolerance of the plants. It's not just a deficiency corrector; it's a plant strengthener. I run it alongside my base Canna fertilizers and other boosters with zero issues. My pro tip? Don't wait for a deficiency to show. Use it proactively at a lower dose. Your plants will build a stronger foundation, and you'll avoid 90% of common grow-room headaches. It's one of those products that just makes growing smoother and more predictable.
