Athena CaMg — 940ml

Athena CaMg — 940ml

Athena CaMg delivers calcium and magnesium supplementation — essential for coco coir growers, RO water users, and soft-water areas where these secondary nutrients are consistently under-supplied by tap water alone. Formulated to integrate cleanly with Athena's base nutrients without causing precipitation or pH instability.

Why growers choose Athena CaMg:

• Calcium + magnesium supplementation — addresses the two most common secondary deficiencies
• Essential for coco and RO water
• Clean integration with Athena base nutrients
• Available 940ml, 3.78L, and 18.92L

Who it's not for:

If growing in soil with hard tap water (above 0.4 EC), you likely have sufficient Ca/Mg already. For comparison: same function as Green Planet Pro-Cal, Canna CalMag Agent, or Remo's MagNifiCal.
