Review: Love this - This CALiMAGic supplement from General Hydroponics has been a total game changer for my plants. If you’re dealing with calcium or magnesium deficiencies, this stuff works fast and reliably. Within just a short time of using it, I noticed stronger stems, healthier leaves, and a deeper, richer green color overall. It really helped clear up the yellowing and spotting I was seeing before, especially in my more sensitive plants. The difference was noticeable enough that I now consider it an essential part of my feeding routine. What I like most is how easy it is to use—it mixes well with water, doesn’t leave any weird residue, and integrates smoothly with my other nutrients without causing issues. The 1-0-0 formula is perfect for supplementing without throwing off the rest of your nutrient balance. The bottle size is also great value for the price. A little goes a long way, so it lasts longer than expected, even with regular use. Overall, this is a must-have if you’re serious about plant health, whether you’re growing in hydroponics or soil. Reliable, effective, and worth every penny—I’ll definitely keep buying this.
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!

## 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
