Cal Mag Plus Concentrate Cal Mag Plus Solution "Greenway Biotech Brand" 25 Pounds = 10 Gallons

Essential Foundation for Complete Hydroponic Nutrition: This product provides 3.2% calcium, 1.2% magnesium, and chelated iron - the vital secondary nutrients that base fertilizers are missing. Part of a 4-part system made for DWC, NFT, ebb and flow, drip systems, and coco coir growing. Always add first before other nutrients. Crucial for RO Water and Coco Coir: Reverse osmosis and distilled water contain zero minerals - this product restores what's absent. Coco coir naturally binds calcium, causing deficiencies even with tap water. Use with every watering in coco at 5-10 ml/gal to prevent lockout and maintain thriving plants. Assists in Preventing Blossom-End Rot and Deficiency Symptoms: Calcium fortifies cell walls to lower the risk of blossom-end rot in tomatoes and peppers when utilized as part of a balanced feeding regimen. Magnesium aids chlorophyll production to prevent interveinal yellowing. Chelated iron stays accessible across a broad pH range to promote healthy new growth. 100% Water Soluble - Zero Residue: Dissolves entirely in seconds for a crystal-clear reservoir solution. No clogged drip lines, no pump damage, no sediment accumulation. Produces a stable stock solution (2.5 lb per gallon) with a storage duration exceeding 6 months. Compatible with all dosing and fertigation equipment. Save 50-70% Compared to Liquid Cal-Mag: Concentrated powder delivers nutrients, not water. One 2.5 lb bag yields the same amount as multiple gallons of liquid product at a fraction of the price. Approximately $0.08 per gallon of working solution. Extended storage duration when kept dry - no waste from expired liquids. Works in All Water Culture Systems: Formulated for recirculating (DWC, RDWC, NFT, ebb and flow) and drain-to-waste systems. Adjust rate based on water hardness: full strength for RO/distilled, 50-75% for soft tap, 25% or skip for hard water. Test your starting EC to determine the ideal amount. Complete 4-Part System Integration: Designed to function with Grow Green (vegetative), Micro Green (trace elements), and Blossom Green (flowering). Always add this product first to water, dissolve completely, then add remaining nutrients in order. Prevents calcium precipitation and keeps all nutrients in solution
