Cutting Edge Solutions Cal-Mag Amplified, 15 gal

Chelated Calcium, Magnesium, and Iron Supplement, 15 Gal

Calcium and magnesium deficiencies show up more often in soilless and coco-based growing media than in native soil, since these media don't hold and buffer secondary nutrients the way soil does. Cutting Edge Solutions Cal-Mag Amplified adds a 2-0-0 base of nitrate nitrogen, calcium, magnesium, and iron in a chelated, pH-stable form so the plant can take these secondary nutrients up reliably across a range of media and water sources.

The 15 gal size fits a larger indoor grow room or small commercial operation running Cal-Mag Amplified through consistent batch mixing.

Key Features & Benefits

• 2-0-0 base with calcium and magnesium — provides 2.0% nitrate nitrogen, 3.5% calcium, and 1.0% water-soluble magnesium, plus 0.1% iron.
• Chelated for stability — calcium and magnesium arrive as calcium nitrate and magnesium nitrate, with iron chelated as iron DTPA, for pH-stable, plant-available minerals.
• 3.5:1 calcium-to-magnesium ratio — the calcium-heavy ratio is built for coco coir and other soilless media where calcium demand runs high.
• Works across feeding methods — suited to drip irrigation, recirculating hydroponic systems, and reservoir feeding through both vegetative and flowering stages.
• Foliar-compatible during veg and transition — can also be applied as a foliar spray during the vegetative and transition phases.

Who Should Use CES Cal-Mag Amplified

Growers working in coco coir, rockwool, or other soilless media who need a reliable calcium and magnesium supplement to prevent lockout, plus growers using RO or soft water sources that carry little calcium or magnesium on their own.

About Cutting Edge Solutions

Founded in 2001 by cultivator John “Uncle John” Piccirilli, Cutting Edge Solutions builds its additive lineup to sit on top of its Micro/Grow/Bloom base rather than replace it. Cal-Mag Amplified is part of the company's Strength family, joining Plant Amp, Mag-Amped, and Uncle John's Blend as a concentrated, targeted supplement. CES keeps its manufacturing domestic, running formulation and bottling out of its own facility in White City, Oregon.

Frequently Asked Questions

What is Cutting Edge Solutions Cal-Mag Amplified?

Cal-Mag Amplified is a 2-0-0 chelated calcium, magnesium, and iron supplement built to prevent secondary-nutrient deficiencies in soilless growing media. It provides 3.5% calcium and 1.0% water-soluble magnesium alongside 2.0% nitrate nitrogen and 0.1% iron.

How much calcium and magnesium does Cal-Mag Amplified provide?

The formula delivers 3.5% calcium and 1.0% magnesium, a 3.5-to-1 ratio, along with 2.0% nitrate nitrogen and 0.1% chelated iron. Calcium and magnesium arrive as calcium nitrate and magnesium nitrate for pH-stable, plant-available uptake.

When do I need a cal-mag supplement?

Soilless media like coco coir and rockwool don't buffer calcium and magnesium the way native soil does, so deficiencies show up more readily, especially with RO or soft water sources. Adding Cal-Mag Amplified to the base feeding program during vegetative and flowering stages helps prevent that shortfall.

Can Cal-Mag Amplified be used as a foliar spray?

Yes, Cal-Mag Amplified can be applied as a foliar spray during the vegetative and transition phases. Dilute to the labeled rate and apply during lights-off or low light, then continue root-zone dosing through the rest of the cycle.

Does Cal-Mag Amplified work with coco coir?

Yes, the 3.5-to-1 calcium-to-magnesium ratio is built with coco coir in mind, since coco holds calcium loosely and requires more supplemental calcium than a typical soil-based program. It's suited to drip, recirculating hydroponic, and reservoir feeding methods in coco or other soilless media.
