Roots Organics CalMag is a pure, all-natural blend of calcium, magnesium, and sulfur designed to support plants during periods of rapid growth. Free of added nitrogen, phosphate, and potassium — giving you full control over your primary fertility inputs without altering NPK ratios.
Why CalMag Matters
Calcium strengthens cell walls and supports fruit development. Magnesium is the central atom in chlorophyll — without it, photosynthesis suffers. Fast-growing plants in containers, coco coir, or RO-filtered water frequently develop cal-mag deficiencies that stunt growth and reduce yields.

- Zero NPK — supplement without affecting your feeding ratios
- Contains sulfur for enhanced nutrient uptake
- Compatible with all organic and natural feeding programs
