Advanced CalMag Hydroponics – Calcium & Magnesium Supplement

Advanced CalMag Hydroponics is the structural reinforcement your crop needs to transform weak stems into heavy-bud-bearing branches. This concentrated supplement provides the exact ratio of Calcium and Magnesium to prevent common deficiencies, ensuring your plants remain vigorous and healthy, especially if you grow with soft water or high-intensity lighting.

Why is Calcium and Magnesium essential for your crop?

Have you started noticing those dreaded rust-colored spots on the leaves or stems that seem too weak to hold the weight of the flowers? These are the classic symptoms of a calcium and magnesium deficiency, a silent enemy that often appears when you least expect it, especially if you strive to give your plants the purest water possible.

The problem is that by filtering the water or using soft water, you remove these essential minerals. If you don't act fast, this lack not only affects the structure of the plant but also blocks the absorption of other vital elements. The result is a stalled crop, yellowing leaves, and a harvest that falls far short of its potential, leaving you frustrated after weeks of hard work.

The solution is simple and effective: Advanced CalMag Hydroponics. This additive is designed to rebalance the profile of your irrigation water, providing the necessary "hard" nutrients so that the plant can build strong cell walls and carry out photosynthesis efficiently. It is the perfect insurance to keep your grow room running at 100% capacity.

How to use Advanced CalMag Hydroponics correctly

Using this supplement is very intuitive, but precision is key to avoiding over-fertilization. It is compatible with any cultivation method, although it shines especially in Hydroponic and Aeroponic Systems where the substrate does not provide nutrients.

• Preventive use: Add it to your water tank before mixing the rest of the fertilizers.
• Dosage: The general recommendation is 1 ml per liter of water, but you should measure the EC (Electroconductivity) to adjust it to your water type.
• Order of mixing: Always add CalMag first, stir well, and then add the base nutrients and stimulators.
• Application frequency: Use it in every irrigation if you use osmosis water. If you use tap water, you may only need it once a week or during peak flowering demand.

Features, Advantages, and Benefits (FAB)

Why should you choose this specific bottle over others? Here is the breakdown of what it brings to your setup:

• Feature: Balanced concentration of Calcium and Magnesium plus 20mg of Nitrogen.
  • Advantage: It covers the two most common deficiencies in a single product without causing nitrogen imbalances.
  • Benefit: You save money and hassle by not having to buy separate mono-nutrients, ensuring your plants stay lush green.
• Feature: Formula optimized for soft and osmosis water.
  • Advantage: It raises the base EC of the water to the optimal starting point (0.4 EC).
  • Benefit: It allows your base Cannabis fertilizers to work perfectly, avoiding pH fluctuations and nutrient lockouts.
• Feature: High bioavailability.
  • Advantage: The plant absorbs minerals immediately, without waiting for them to break down in the substrate.
  • Benefit: You see results in a matter of days; the spots stop spreading and the new growth comes out healthy and strong.

Frequently Asked Questions

When should I start using CalMag?

You can use it from the vegetative phase, especially if you see that the stems are weak or if you are growing in coco coir, which tends to sequester calcium. It is crucial during the transition to flowering when the plant stretches.

Is it necessary if I use tap water?

It depends on the hardness of your water. If your tap water has an EC greater than 0.4 or 0.5, you probably don't need it regularly. However, under powerful LED lights, plants consume much more calcium, so a supplement might still be necessary.

Can I use it as a foliar spray?

Yes, in cases of severe deficiency, you can apply it sprayed on the leaves (at a lower dose and with lights off) for faster absorption, but root application is always more stable for long-term maintenance.

Personal Experience of Pevgrow’s CEO (Alan)

I remember when I switched to LED lighting a few years ago; suddenly, my usual recipe stopped working. The plants looked sad, with rusty spots, even though I was controlling the pH perfectly. I thought it was a fungus until I realized that the metabolic rate under LEDs devours calcium. Incorporating Advanced CalMag was the "magic" fix. My advice: if you use an osmosis filter, never forget this bottle. It's the foundation upon which the rest of the nutrition is built; without a good CalMag base, even the most expensive booster won't do its job.
