Grow More® Mendocino N-Cal-Mag — 6 gal

Liquid Calcium and Magnesium Supplement, 6 gal, Built to Improve Phloem Nutrient Flow

Calcium and magnesium deficiencies rarely show up as a simple, isolated shortage — they show up as tip burn, blossom end rot, and interveinal chlorosis that a standard fertilizer program doesn't fully prevent. Grow More Mendocino N-Cal-Mag goes beyond just supplying calcium and magnesium, adding nitrate nitrogen specifically chosen to enhance mass flow within the phloem, the plant's main transport channel, so carbohydrates and other nutrients move through the plant more efficiently.

Available in 6 gal, N-Cal-Mag suits everything from boutique growing setups to larger commercial production, supplying 3.0% calcium, 2.2% magnesium, and 2.2% nitrate nitrogen in a fully soluble liquid concentrate.

Key Features & Benefits

• Targeted Ca-Mg-N Formula: Supplies 3.0% calcium, 2.2% magnesium, and 2.2% nitrate nitrogen, the three nutrients most often deficient in RO-water and soilless programs.
• Enhances Phloem Mass Flow: Improves nutrient mass flow within the plant's vascular system, supporting more efficient carbohydrate and micronutrient translocation.
• Prevents and Corrects Deficiency Disorders: Heads off and rapidly corrects tip burn, blossom end rot, interveinal chlorosis, and poor fruit set.
• Nitrate Nitrogen Source: Supplies immediately available nitrogen that supports cellular function without pushing excess vegetative growth.
• Liquid Concentrate: Fully soluble and fast-acting, mixing easily into reservoirs and irrigation water.

Who Should Use This

Hydroponic growers, coco coir cultivators, and anyone using reverse osmosis or soft water as a primary source — where calcium and magnesium levels typically fall short of plant demand — are the direct fit. It is particularly valuable during rapid vegetative growth and again through flowering and fruiting, when calcium demand for cell-wall integrity peaks.

About Grow More Inc.

Grow More Inc., founded in 1918 as National Chemical Company in Hollywood, California and now based in Gardena, California, builds its Mendocino nutrient line — including N-Cal-Mag — around correcting the deficiencies common in RO-water and soilless growing programs.

Frequently Asked Questions

What distinguishes N-Cal-Mag from a standard Cal-Mag supplement?

N-Cal-Mag includes 2.2% nitrate nitrogen alongside calcium and magnesium. That nitrate form is specifically chosen to enhance phloem mass flow, improving overall nutrient utilization beyond simply correcting a Ca-Mg shortfall.

What are the symptoms of calcium deficiency I should watch for?

Calcium deficiency typically shows up first on new growth: brown, necrotic leaf tips, curling or cupping leaves, distorted growing tips, and blossom end rot on fruiting crops. Because calcium moves poorly within the plant, symptoms appear on young tissue rather than older leaves.

When should I start using N-Cal-Mag in my feeding program?

It can be used from the early vegetative stage onward as a preventive measure, especially in RO-water systems. Supplementation needs typically rise as plants enter rapid vegetative growth and again during early flowering when calcium demand peaks.

Is N-Cal-Mag safe for recirculating hydroponic systems?

Yes, it's formulated for use in all growing systems, including recirculating hydroponics. It dissolves fully without leaving sediment and fits standard reservoir management practices, including regular pH and EC monitoring.
