Cutting Edge Solutions Cal-Mag Amplified, 6 gal

Cal-Mag Amplified — Calcium and Magnesium Supplement for Hydroponics and Coco Coir, 6 gal

Calcium and magnesium are among the most frequently depleted secondary macronutrients in hydroponic and coco coir growing. Magnesium is the central atom of the chlorophyll molecule, making it essential for light capture and photosynthesis — a deficiency shows quickly as interveinal chlorosis. Calcium is essential for cell wall development and integrity, and also plays a role in regulating the uptake of other cations in the root zone. Both nutrients work best when delivered in a pure, highly soluble form that is immediately available to the plant.

Cutting Edge Solutions Cal-Mag Amplified delivers calcium and magnesium in pure, rapidly absorbable forms. Coco coir growers benefit particularly from supplemental calcium, which buffers the substrate and maximizes cation exchange capacity — allowing the medium to hold and release nutrients effectively. Magnesium in Cal-Mag Amplified drives chlorophyll production and supports photosynthesis, while calcium fortifies cell walls and supports fruit set. Foliar application is recommended for faster results; apply at sunrise or sunset when stomata are fully open, delivering calcium directly through the apoplast pathway to fortify cell walls and free mobile calcium for fruit set. Available in six gallons.

Key Features & Benefits

• Pure calcium and magnesium — delivers both calcium and magnesium in pure, rapidly absorbable forms — no fillers, no dyes.
• Coco coir buffer — additional calcium buffers coco coir substrate, maximizing cation exchange capacity and allowing the medium to hold and release nutrients effectively throughout the grow.
• Magnesium for chlorophyll production — magnesium is the central atom of the chlorophyll molecule; adequate Mg supply drives chlorophyll synthesis and maximizes photosynthetic rate.
• Calcium for cell walls and fruit set — calcium fortifies cell walls throughout the plant and, when applied as a foliar, travels through the apoplast pathway to free mobile calcium for active fruit set.
• Foliar-ready — suitable for foliar application; apply at sunrise or sunset when stomata are fully open for maximum calcium absorption through the apoplast pathway.

Who Should Use CES Cal-Mag Amplified

Hydroponic growers, coco coir cultivators, and any grower whose water source or base nutrient program is low in calcium or magnesium — or who grows plant varieties with elevated Ca or Mg demand. Also valuable as a foliar supplement for direct cell wall calcium delivery and fruit set support.

Coco Coir and Calcium Supplementation

Coco coir naturally holds calcium ions and can strip them from nutrient solution if not pre-buffered. Cal-Mag Amplified provides the additional calcium needed to saturate the cation exchange sites in coco, preventing the medium from depleting Ca from the root zone. Once buffered, coco maximizes its cation exchange capacity and delivers nutrients to the root zone efficiently. For foliar use, dilute to the recommended rate and apply at sunrise or sunset when stomata are dilated for best results.

Frequently Asked Questions

What is Cutting Edge Solutions Cal-Mag Amplified?

Cal-Mag Amplified is a calcium and magnesium supplement that delivers both nutrients in pure, rapidly absorbable forms. It is designed for hydroponic growers, coco coir cultivators, and any grower who needs to increase calcium and magnesium levels in their nutrient program. It is also suitable for foliar application.

Why do coco coir growers especially benefit from Cal-Mag Amplified?

Coco coir has a naturally high cation exchange capacity but holds calcium ions tightly. If not pre-buffered with calcium, fresh coco can strip Ca from the nutrient solution before the plant can uptake it. Cal-Mag Amplified provides the supplemental calcium needed to saturate coco's exchange sites, maximizing CEC and ensuring consistent nutrient delivery to the root zone.

How does magnesium support plant growth?

Magnesium is the central atom of the chlorophyll molecule and is essential for photosynthesis. Without adequate magnesium, the plant cannot produce sufficient chlorophyll to collect light energy. Mg deficiency typically appears as interveinal chlorosis — yellowing between the leaf veins — on older leaves first. Cal-Mag Amplified provides rapidly absorbable magnesium to prevent and correct deficiency.

How does foliar application of Cal-Mag Amplified work?

Calcium applied as a foliar spray is absorbed through the apoplast pathway — traveling through the cell wall spaces between plant cells rather than through the phloem. This delivers calcium directly to cell walls and frees mobile calcium to support active fruit set. Apply at sunrise or sunset when stomata are fully open for maximum absorption.

Can Cal-Mag Amplified be used with the CES 3-part base nutrient system?

Yes — Cal-Mag Amplified is a supplement designed to stack on top of a base nutrient program. Use it whenever calcium and magnesium levels need to be raised above what the base formula provides. Follow the CES usage guide for compatible dosing alongside CES Micro, Grow, and Bloom.
