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!

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.

By supplying these secondary nutrients in a concentrated form, CALiMAGic optimizes cannabis growth and helps achieve better yields. Furthermore, CALiMAGic's versatility makes it an ideal choice for indoor cannabis growers. Whether you prefer soil, coco coir, or hydroponic setups, CALiMAGic seamlessly integrates into any growing medium.

Great product that does what as advertised!!!
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%

Can’t grow orchids without it!
Calcium is the most important immobile nutrient to orchid growth. In the wild, they have a constant, steady supply of calcium from the tree they’re mounted to every time it rains. For every percent of nitrogen you give to your orchids, you want to at least match the calcium percentage (a little more just in case is better). I use this to supplement my Tezula MSU to raise the calcium up. 100-130ppm of MSU, and 20ppm of Cali-Magic. Works great!

自作水耕栽培器でトマトを毎年育てています。 尻腐れが発生するので購入してみました。 結果、尻腐れは、無くはないですが、実付きの割には非常に少なくなりました、効果あると思います。
