Ata Calmag Atami – Calcium & Magnesium Additive for Soft Water

Ata Calmag by Atami is the professional additive you need to provide that crucial extra supply of Calcium and Magnesium your crop is screaming for. If you grow with soft water or simply want to ensure an iron-clad structure for your plants, this nutrient cocktail is the key to unlocking their full potential and avoiding the dreaded deficiencies that ruin harvests.

Why are your plants asking for help?

Have you noticed yellow spots appearing on the leaves, weak stems, or a pale green color just when everything seemed to be going well? You are likely facing a nutrient imbalance.

It is incredibly frustrating. You invest in the best genetics and lights, but your "girls" look sad and lack energy. This is often a "silent killer": the lack of Calcium and Magnesium. If you don't fix it fast, photosynthesis slows down, growth stunts, and you end up with a mediocre harvest that doesn't reflect your hard work.

Ata Calmag solves this problem instantly. It restores the nutrient balance, ensuring your plants have the "bricks" (Calcium) to build strong cell walls and the "energy engine" (Magnesium) to keep photosynthesis running at 100%. It turns a fragile crop into a green, robust jungle.

What exactly does Ata Calmag deliver?

This additive is a fast-acting solution developed by Atami to supplement the base nutrition of your plants. It is specifically formulated to buffer soft water or demineralized water, but it works wonders as a booster in any setup.

• Optimal Ca/Mg Ratio: Provides the perfect balance so you don't have to mix separate powders.
• Nitrogen Boost: Includes a touch of Nitrogen to support vegetative growth and keep leaves deep green.
• Versatility: Works perfectly in soil, coco, and Hydroponic and Aeroponic Systems.
• Fast Absorption: The chelated formula allows the plant to drink it up immediately, fixing deficiencies in record time.

How your routine changes from now on

Forget about waking up to find rust spots on your fan leaves. By adding Ata Calmag to your irrigation tank, you stabilize the water quality, creating the perfect foundation for your base nutrients to work effectively. Your plants will look perkier, with thicker stems capable of supporting heavy buds later on.

It also takes the stress out of using RO (Reverse Osmosis) water. You no longer have to worry about "stripping" the water too much; you simply add this additive to reach your desired starting EC (usually 0.4 mS) and you are good to go.

Advantages and benefits you'll notice from day one

• Prevents Nutrient Lockout: Because it balances the water, it helps plants uptake other nutrients more efficiently, which means healthier growth.
• Stronger Structure: Calcium is essential for cell division. You will see thicker branches that don't snap under the weight of flowers.
• Greener Leaves: Magnesium is the core of the chlorophyll molecule. Using this means lush, vibrant foliage that processes light efficiently.
• Essential for LED Growers: LED lights increase the plant's metabolic rate and demand for CalMag. This product prevents the specific deficiencies common in modern indoor grows.
• Cost-Effective: A small dose goes a long way, saving you money by preventing crop failure due to deficiencies.

Tips to combine it with other products

Ata Calmag is compatible with almost any fertilizer brand, but it shines when used with the Atami range. Remember to add it to your water before your base nutrients. Since it affects the Electro-conductivity (EC) of your solution, it is vital to use precise PH meters and EC meters to keep everything in the sweet spot.

• For Soil: Mix it with your Universal Substrate irrigation if you are using soft tap water.
• For Coco/Hydro: It is practically mandatory to use it in every watering to buffer the medium.

Frequently Asked Questions

When should I use Ata Calmag?

You should use it throughout the vegetative stage and the first weeks of flowering, especially if you use soft water (EC < 0.4) or reverse osmosis water. It's also used curatively if you see deficiency signs.

What is the recommended dosage?

The standard dose is between 0.1 ml and 1 ml per liter of water. Start low and increase until your base water reaches an EC of roughly 0.4 mS before adding other fertilizers.

Can I use it as a foliar spray?

Yes, for quick correction of deficiencies, you can spray it on the leaves (diluted, approx 0.5 ml/L) just before the lights go off to avoid burns.

Personal Experience of Pevgrow's CEO (Alan)

I've learned the hard way that you can't trust tap water blindly, and if you filter it, you strip away the good stuff too. I started using Ata Calmag when I switched to LED lighting; my plants were eating up Magnesium like crazy and showing spots overnight. Since I incorporated this bottle into my routine, specifically bringing my RO water up to 0.4 EC before adding anything else, the stability of my crops has improved 100%. It's one of those "boring" products that you don't appreciate until you see the disaster of not having it. If you want professional results, don't skip this step.
