Ours carries kelp extract — a natural source of nitrogen, auxins, cytokinins and other phytohormones, plus micronutrients competitors leave out — which also assists chelation and pulls more of your feed into the plant instead of into the medium.\u003c\/p\u003e\n\u003cp\u003eCalcium and magnesium deficiencies happen in any garden, but some media stack the odds against you. Coco coir in particular can lock out a share of the calcium and magnesium you feed. Calcium lengthens roots and builds cell walls; magnesium activates the enzymes behind nutrient absorption and is a literal component of chlorophyll. Short either one and photosynthesis, growth and flowering all pay for it.\u003c\/p\u003e\n\u003ch3\u003eGuaranteed analysis — 2-0-0\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTotal nitrogen 2.0% (0.1% ammoniacal, 1.9% nitrate)\u003c\/li\u003e\n\u003cli\u003eCalcium 3.0% · Magnesium 0.5% water-soluble\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDerived from\u003c\/strong\u003e ammonium calcium nitrate double salt, magnesium sulfate, calcium acetate, magnesium acetate, kelp extract\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to run it\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAs needed rather than as part of the regular schedule — during rapid vegetative growth, in transition, or at peak flowering.\u003c\/li\u003e\n\u003cli\u003eSoak coco coir and other soilless media with Cal-Mag before planting.\u003c\/li\u003e\n\u003cli\u003eUseful insurance when running another brand’s base that may not carry a full essential set.
