Grow More® Mendocino N-Cal-Mag — 2.5 gal

Correct Calcium and Magnesium Deficiencies and Improve Nutrient Translocation with Grow More N-Cal-Mag

Grow More® Mendocino N-Cal-Mag is a precisely formulated liquid nutrient solution developed to address the physiological nutrient disorders that result from calcium and magnesium deficiencies. Beyond simply supplying Ca and Mg, N-Cal-Mag is engineered to enhance the mass flow of nutrients within the phloem — the plant’s primary nutrient transport highway — improving the translocation of carbohydrates and other compounds throughout the plant for healthier, more productive growth. Available in 2.5 gal.

Key Features & Benefits

• Targeted Ca-Mg-N Formula: Supplies 3.0% calcium, 2.2% magnesium, and 2.2% nitrate nitrogen — the three nutrients most commonly deficient in fast-growing crops in hydroponic and soilless systems, and in RO-water programs.
• Enhances Phloem Mass Flow: The specific formulation improves nutrient mass flow within the plant’s vascular system, supporting more efficient translocation of carbohydrates and micronutrients from source to sink tissues throughout the plant.
• Prevents and Corrects Deficiency Disorders: Proactively prevents and rapidly corrects the tip burn, blossom end rot, interveinal chlorosis, and poor fruit set that result from inadequate calcium and magnesium availability.
• Nitrate Nitrogen Source: The 2.2% nitrate nitrogen provides an immediately available nitrogen form that supports cellular function and phloem loading without contributing to excess vegetative growth.
• Liquid Concentrate: Fully soluble and fast-acting — mixes easily into nutrient reservoirs and irrigation water for rapid plant uptake.
• Available in 2.5 gal: Sized for everything from boutique growing operations to large-scale commercial production facilities.

Who Should Use This

N-Cal-Mag is an essential supplement for hydroponic growers, coco coir cultivators, and any grower using reverse osmosis or soft water as their primary water source, where calcium and magnesium are not present at adequate levels to meet plant demand. It is particularly valuable during the rapid vegetative growth phase and through flowering and fruiting when calcium demand for cell wall integrity is highest.

Compatibility

N-Cal-Mag is compatible with soil, coco coir, soilless mixes, and all hydroponic delivery systems. It can be used alongside most conventional and organic nutrient programs. When mixing your reservoir, add N-Cal-Mag before other concentrated nutrients and pH-adjust after all nutrients have been thoroughly mixed. Available in 2.5-gallon and 6-gallon sizes.

Frequently Asked Questions

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

N-Cal-Mag includes 2.2% nitrate nitrogen in addition to calcium and magnesium. The nitrate form of nitrogen is specifically chosen to support and enhance phloem mass flow — the process by which nutrients and carbohydrates are transported through the plant — which improves overall nutrient utilization efficiency beyond simply correcting Ca-Mg deficiency.

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

Calcium deficiency typically appears first on the newest growth: brown, necrotic leaf tips, curling or cupping of new leaves, distorted growing tips, and blossom end rot on fruiting crops. Because calcium is relatively immobile in plants, deficiency symptoms appear on young tissue rather than older leaves.

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

N-Cal-Mag can be used from the early vegetative stage onward as a preventive measure, particularly in RO-water systems. The need for supplementation generally increases as plants size up and enter rapid vegetative growth and again during the early flowering stage when calcium demand for cell wall development peaks.

Can N-Cal-Mag replace both a nitrogen supplement and a Cal-Mag supplement?

N-Cal-Mag provides moderate levels of all three nutrients, making it an efficient multi-function supplement. However, for crops with very high nitrogen demands or severe Ca-Mg deficiencies, additional targeted supplementation may still be needed alongside N-Cal-Mag. Always monitor plant response and adjust feeding rates accordingly.

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

Yes. N-Cal-Mag is formulated for use in all growing systems, including recirculating hydroponics. It dissolves fully without leaving sediment and is compatible with standard hydroponic reservoir management practices including regular pH and EC monitoring.
