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 dial in the perfect amount.\n- COMPLETE 4-PART SYSTEM INTEGRATION: Designed to work with Grow Green (vegetative), Micro Green (trace elements), and Blossom Green (flowering). Always add Cal-Mag first to water, dissolve fully, then add remaining nutrients in order. Prevents calcium precipitation and keeps all nutrients in solution.\n- LED GROWS MAY NEED MORE CAL-MAG: High-intensity LED lighting increases transpiration rates, pulling more calcium through plants faster. Many growers report slightly higher Cal-Mag rates under LEDs compared to HPS. Monitor for tip burn and adjust accordingly - prevention is easier than correction.\n- HEAVY METAL TESTED FOR FOOD-SAFE GROWING: Every batch is laboratory tested to verify freedom from heavy metal contamination. CDFA registered and manufactured in California, USA since 1989. When growing consumable crops, purity matters - trust a company with 35+ years serving serious growers.\n- WHO THIS IS NOT FOR: This is a concentrated supplement requiring mixing, measuring, and EC monitoring - not a complete standalone fertilizer. If you have hard tap water (EC above 0.5), you may not need additional Cal-Mag. Not recommended for soil growing or gardeners wanting pre-mixed solutions. Test your water first.\n\u003c\/p\u003e\u003cp\u003eProduct description\u003c\/p\u003e\u003cp\u003eCal Mag 2-0-0 Plus Iron EDTA\u003c\/p\u003e\u003cp\u003eHow to Apply Greenway Biotech Cal Mag Plus\u003c\/p\u003e\u003cp\u003eHow to Apply Greenway Biotech Cal Mag Plus\u003c\/p\u003e\u003cp\u003eHow to Apply Greenway Biotech Cal Mag Plus\u003c\/p\u003e\u003cp\u003eHow to Apply Greenway Biotech Cal Mag Plus\u003c\/p\u003e\u003cp\u003eOur Core Values\u003c\/p\u003e\u003cp\u003eGreenway Biotech's Cal Mag Plus contains a balanced ratio of Calcium, Magnesium, and Iron, which are critical throughout all stages of growth, especially in heavily blooming plants and annuals. Calcium and Magnesium are necessary for the prevention of blossom end rot in tomatoes and peppers, as well as the reduction of tip burn in lettuce.
