CaMg

Athena CaMg is a liquid calcium, magnesium, iron, and nitrogen supplement with an NPK of 2-0-0, specifically designed to correct the most common deficiencies encountered when growing with reverse osmosis (RO) water or in inert media like coco coir and rockwool. RO water strips naturally occurring calcium and magnesium, and coco coir is calcium-hungry — meaning Ca/Mg supplementation is nearly mandatory in these setups.

The 2-0-0 formula adds nitrogen alongside the calcium and magnesium, providing a balanced uptake ratio that reflects how plants naturally use these elements together. Iron is included because magnesium and calcium deficiencies often coincide with iron availability issues. The liquid form ensures immediate availability compared to dry amendments.

Designed to supplement Athena's two-part liquid base nutrients (Blended or Pro Line) rather than as a standalone feed. Use from early vegetative growth through flowering at dosages recommended on Athena's feed charts, adjusting based on your water source and media. Made by Athena, Los Angeles — a professional-grade nutrient brand built in and for commercial cannabis production.
