Review: Great Supplement for Preventing Nutrient Deficiencies in Hydroponic Systems - I’ve been using General Hydroponics CALiMAGic for the past few months in my hydroponic grow system, and it has made a noticeable difference in the health and growth of my plants. If you're experiencing calcium or magnesium deficiencies in your plants, this product is a lifesaver. Pros: Effective at preventing nutrient deficiencies: After incorporating CALiMAGic into my nutrient schedule, I saw immediate improvement in leaf quality. Prior to using this, my plants had signs of calcium deficiency (yellowing leaves with brown spots). Within a week, new growth appeared healthy, and the discoloration stopped spreading. Easy to use and mix: I appreciate how quickly it dissolves into the nutrient solution. It doesn’t leave any sediment or cloudiness, which is crucial for maintaining my recirculating deep water culture (RDWC) setup. Versatile for different plants: I’ve used this product on a variety of crops, including leafy greens, tomatoes, and cannabis, and it works equally well across the board. The added magnesium especially helps with chlorophyll production, leading to lusher and more vibrant growth. Cons: Concentration can be tricky: CALiMAGic is highly concentrated, which is great for efficiency, but beginners might overuse it if they're not careful. Be sure to follow the dosage instructions carefully. I recommend starting with half the suggested dose if you’re unsure, then adjusting based on how your plants respond. Price: While the product isn’t overly expensive, there are cheaper alternatives on the market. However, in my experience, CALiMAGic is worth the extra cost because of its consistency and reliability. Overall Experience: After using this product consistently, I’ve noticed my plants are more resistant to stress, and their growth is more robust. It has become a staple in my nutrient regimen, especially for hydroponics. If you're serious about growing healthy plants, CALiMAGic is a must-have. Tips for Use: Monitor your pH: CALiMAGic can slightly raise the pH of your nutrient solution. Make sure to check your pH levels after mixing to avoid any imbalances. Combine with a complete nutrient system: While CALiMAGic addresses calcium and magnesium needs, it’s important to pair it with a balanced nutrient base to cover all of your plants’ requirements. --- I highly recommend General Hydroponics CALiMAGic to anyone who’s serious about their hydroponic system, especially for preventing deficiencies that can halt plant growth. It’s a small investment for big results!
Review: Essential affordable and quality health - General Hydroponics CALiMAGic is an exceptional product that holds numerous benefits for indoor cannabis cultivation. With its concentrated blend of calcium and magnesium, it addresses crucial nutrient deficiencies and enhances the growth and development of cannabis plants in hydroponic systems. One of the key benefits of CALiMAGic is its ability to prevent blossom end rot and tip burn. These issues commonly affect cannabis plants and can lead to reduced yields and compromised quality.

## Questions & Answers

**Q: Is this organic?**
A: This product is not organic. General Hydroponics has a sister brand General Organics which has CAMG+ which is here: http://www.amazon.com/General-Hydroponics-Organics-CaMg-Gal/dp/B007RQSPG6/ref=sr_1_3?ie=UTF8&qid=1432227928&sr=8-3&keywords=general+organics+camg%2BAs mentioned, organics is different. Just be sure to have good biology going on in your roots. Try organic compost teas such as Organics Alive or Earth Juice's Bio-Righteous to really boost biology and help nutrient breakdown.

**Q: Does this lower ph?**
A: It should lower ur ph . My tap is 7.8 after adding all my stuff my ph is 6.4 . ... run cal mag lil higher then bottle shows I run mine at 3ml gal thing bottle says 1-2ml and I also run it all way threw , I'm using tap water at 89 to 114 ppm .. hope that helps ..

**Q: Do i add this before armor si to Ro water? Or the other way around?**
A: You absolutely add the Si first, and its recommended to wait 1hr. after adding the Si before checking the T.D.S.(total dissolved solids), and checking the P.h. I will add my Si to a bunch of my gal. jugs of water close the cap and set them aside till the next day then add my cal-mag and the rest of my nutrients. Its just the way I do it, but you should wait the hour before checking if you want a very accurate reading.

**Q: Does this contain silica.**
A: No it dont i use gh armor si with it its the best and highest concentrate of silica and very reasonably priced

### ⭐⭐⭐⭐⭐ Great product that does what as advertised!!!
*by M***E on September 25, 2025*

I've used this product and have had great results. I used this all across the garden this year. I have been gardening for a few years now. This has been the most successful year for me. My garden bed is up against my neighbor's. He is an older Italian guy that has been growing for decades. His garden has the same conditions as mine as far as temp and sunlight. He very clearly expressed his frustration that my plants thrived so well this year. Lol. I'm located in northern ma ,and currently heading into October and all my plants are still producing and thriving. This will be the first year that frost will end my crop instead of the passing of time. I will buy again for next year 100%
