Lotus Nutrients Cal-Mag Pro Series, Calcium Magnesium Supplement for Hydroponic Plants, Water Soluble Powder for Coco Coir, LED Grows, and RO Water, Indoor and Outdoor Gardens (15oz)
PREVENTS CALCIUM AND MAGNESIUM DEFICIENCY BEFORE IT STARTS: Lotus Cal-Mag delivers bioavailable calcium and magnesium in a fast-dissolving powder that corrects and prevents the yellowing, brown spots, and stunted growth caused by cal-mag lockout. Essential during both vegetative and flowering stages.
BUILT FOR COCO COIR, LED ENVIRONMENTS, AND FILTERED WATER: Coco coir naturally binds calcium, creating deficiency even when your base nutrients contain it. LED grow lights drive faster photosynthesis, increasing calcium and magnesium demand. Reverse osmosis and filtered water strips these minerals entirely. Cal-Mag Pro Series addresses all three scenarios.
ONE POWDER FOR EVERY GROWER AND EVERY MEDIUM: Hobbyists running a single tent, commercial facilities managing hundreds of plants, and soil gardeners supplementing outdoor beds all use the same simple ratio. No separate A and B bottles. No complex mixing sequences. One scoop dissolves completely with no residue.
COMPLETES THE LOTUS PRO SERIES FEEDING PROGRAM: Cal-Mag works alongside Lotus Grow during veg and Lotus Bloom plus Lotus Boost during flowering. The Lotus Intro Kit includes sample sizes of all four products so growers can test the full system before committing. One brand, one feeding chart, consistent results.
100% WATER SOLUBLE WITH NO SEDIMENT OR LINE CLOGGING: Unlike liquid cal-mag supplements that settle and separate, Lotus Cal-Mag powder dissolves fully in seconds. Safe for drip irrigation, automated dosing systems, hand watering, and reservoir mixing. Clean solution every time, no shaking required.
