Athena CaMg — Professional Calcium/Magnesium Supplement

Athena CaMg — Professional Ca/Mg/Fe/N Deficiency Corrector

Designed to supplement Athena's 2-part liquid base nutrients — some cultivars and growing conditions demand higher doses of calcium, magnesium, iron, and nitrogen during heavy growth and development phases than standard feeding provides. Athena CaMg effectively corrects these common deficiencies without throwing off the overall elemental balance of your feeding solution.

Why growers choose Athena CaMg:

• Supplements Athena 2-part liquid formulas — matched compatibility with the Athena programme
• Supplies Ca, Mg, Fe, and N — four commonly-deficient nutrients in one bottle
• Corrects common deficiencies — tip burn, leaf spotting, chlorosis addressed
• Maintains elemental balance — doesn't over-shift other nutrient ratios like single-nutrient additives can
• Useful for high-demand cultivars — some genetics demand more Ca/Mg than generic feeding provides
• Supplement during heavy growth phases — when base feeds can't keep up with demand
• Effective in RO-water systems — RO strips Ca/Mg, this re-supplies them

Who it's not for:

For strict-organic growing, Athena CaMg uses synthetic mineral sources — not organic-certified. For hard UK tap water growers (already high Ca/Mg), this is often unnecessary; check your water EC first. Canna CalMag, Bio-Green X-Cell, or generic CalMag products are cheaper alternatives if you don't need the Athena-specific integration. Not a base nutrient — use alongside a full feeding programme.
