Monkey Nutrients Mag-Cal – Magnesium & Calcium Supplement for Fast-Growing Plants

Monkey Nutrients Mag-Cal – Magnesium & Calcium Supplement

Monkey Nutrients Mag-Cal is a concentrated magnesium and calcium supplement formulated to prevent and correct the most common secondary nutrient deficiencies in fast-growing plants. Magnesium is the central atom of chlorophyll and essential for photosynthesis, while calcium is critical for strong cell wall development and overall plant structure.

Deficiencies in either element are among the most common issues in hydroponic and coco growing, where these nutrients aren’t naturally present in the substrate. Mag-Cal provides both in a highly bioavailable form, keeping your plants healthy and productive throughout the grow cycle.
