Good addition but leaves a mess.
The content itself is worth the money but I wish the bottle would’ve had a spout to make it easier to dose.

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!

I've done a ton of research when deciding my cocktail of nutrient water for my mostly tropical plants... They say to use this every couple weeks but I just use half a dose in my water and use it weekly! I add 2.5ml per gallons of water. The plants have thrived since I started giving then my special water mix! Just some advice, if you're deciding to out the work and research in for your plants you need to invest in a PH meter and PPM meter.. I got both on here for around $25 I believe and they work great! When you're using silicone for your plants especially, you need to make sure your PH is correct and if you're adding a bunch of nutrients and fertilizer, you need to make sure your PPMs are between 6-1500 so you don't kill/burn your plants!
