General Hydroponics CALiMAGic 1-0-0
CALiMAGic 1-0-0 is a concentrated calcium and magnesium supplement formulated to help prevent secondary nutrient deficiencies in fast-growing plants. It supplies readily available calcium and magnesium that support strong cell structure and nutrient transport, addressing common issues such as tip burn and blossom end rot. The highly soluble liquid formulation will not clog spray lines or drip emitters. It is designed to fill uptake gaps that appear when growth outpaces nutrient supply.
Use CALiMAGic at a standard rate of 5 mL per gallon of water (1 tsp per gallon), or up to 10 mL per gallon (2 tsp per gallon) for heavy-feeding programs. Add it after base nutrients but before pH adjustment, mix thoroughly, then monitor EC and pH. It is compatible with reservoirs and automated irrigation systems and can be combined with many other fertilizers. Use it continuously through growth stages where calcium and magnesium demand is high.
