Description

Cal-mag support built for intensive feeding programmes

Athena CaMG is a concentrated secondary nutrient supplement that corrects calcium and magnesium shortfalls in fast-growing, heavily-fed crops. It maintains the critical mineral ratio plants need for cellular integrity and metabolic function, and is designed to slot into your existing feed schedule rather than replace it - topping up the two elements base nutrients often can't supply in the quantities intensive grows demand.

Seeing interveinal yellowing or stretched, weak stems despite a full feed?

Calcium and magnesium deficiencies show as magnesium-induced chlorosis between the leaf veins, blossom end rot, and internode stretch from weak cell structure - all common where these minerals get used up quickly under intensive feeding or bright lighting. Athena CaMG holds the mineral ratio steady and heads off these symptoms before they cost yield.

Key Benefits

  • Corrects Ca/Mg imbalances - targets deficiencies common in intensive growing environments
  • Prevents blossom end rot - maintains calcium supply through flowering and fruiting
  • Prevents magnesium-induced chlorosis - keeps leaves green and photosynthesising efficiently
  • Reduces internode stretch - supports stronger cellular structure
  • Integrates with any feed - concentrated formula added alongside your base nutrients

How to Use

  • Add to reservoir: dose CaMG into your feed water alongside base nutrients, to the rate on Athena's Blended Line feed chart for your stage and system
  • When to use: run across the whole cycle, increasing the rate in coco or under intensive lighting where Ca/Mg demand peaks
  • Set pH: hold pH 5.8-6.2 in hydro and coco after mixing
  • Tip: confirm strength by EC and watch new growth for deficiency clearing
