The Grow Awards 2026 🏆
CalMag Pro provides the calcium and magnesium cannabis plants need for strong growth, especially in coco or soft water setups. Deficiencies in these elements can cause weak stems, leaf spots, or poor nutrient uptake. CalMag Pro fixes that fast. It also contains trace elements to support overall plant health. Use it preventively or at the first sign of imbalance. Whether you’re mixing your own nutrients or just want peace of mind, this is your shield against silent yield killers. For optimal plant health, be sure to check out Plagron’s line of additives including Silic Rock and Pure Zym.
