The details

Meet your next everyday essential.

Athena CaMg delivers a concentrated blend of calcium, magnesium, iron, and nitrogen to support vigorous plant development during heavy growth phases. Designed to work seamlessly with Athena’s 2-part liquid nutrient systems, it helps correct common deficiencies without disrupting elemental balance. This clean, stable liquid formula is especially valuable for growers using reverse osmosis (RO) water or inert media like coco and rockwool, where extra Ca and Mg are often required. By strengthening plant structure and enhancing metabolic activity, CaMg supports robust growth and overall plant vitality in demanding conditions.
