Boca Hydro Cal Mag

Boca Hydro Cal-Mag + Iron

Water-Soluble Nitrate-Based Calcium, Magnesium & Chelated Iron for Hydroponics, Coco, Soil and Fertigation

Boca Hydro Cal-Mag + Iron is a fully water-soluble, nitrate-based calcium and magnesium fertilizer designed for hydroponics, coco, soil, containers, fertigation and foliar feeding. Made with Boca Hydro Calcium Nitrate, Boca Hydro Magnesium Nitrate and added chelated Iron DTPA, this formula supplies essential calcium for strong cell walls, magnesium for chlorophyll production and iron to support deep green growth and healthy new leaves.

Calcium and magnesium are two of the most important secondary nutrients in fast-growing plants, especially in hydroponics, coco, fruiting crops, tomatoes, peppers, citrus, ornamentals and heavy-feeding gardens.

This clean nitrate-based formula dissolves quickly, feeds efficiently and helps correct common Cal-Mag deficiencies caused by soft water, reverse osmosis water, coco coir, heavy fruiting, rapid growth and high-potassium feeding programs.

Product Benefits

Calcium Support	Supplies highly soluble calcium to support strong cell walls, active growing points, healthy roots and developing fruit.
Magnesium for Chlorophyll	Magnesium is a central component of chlorophyll and supports photosynthesis, healthy green foliage and vigorous plant growth.
Chelated Iron DTPA	Added DTPA-chelated iron helps support deep green growth and healthy developing leaves.
Hydroponics & Coco	Ideal for hydroponic systems, coco coir and other intensive growing programs where calcium and magnesium demand can be high.
Fruiting Crops	Supports plants through vegetative growth, flowering, bloom and fruit production.
Clean Nitrate-Based Formula	Made with calcium nitrate and magnesium nitrate for rapid water solubility and efficient nutrient delivery.

Stock Solution & Mixing Reference

Stock Solution	Dissolve 1,000 grams (2.2 lbs) of Boca Hydro Cal-Mag + Iron in 1 gallon of distilled water. Mix thoroughly until fully dissolved.
Best Accuracy	Use a digital pocket scale for accurate measurement, especially for hydroponics, foliar feeding and concentrated stock solutions.
Concentrate Compatibility	Do not mix concentrated Cal-Mag stock directly with phosphate or sulfate concentrates.
Final Irrigation Water	Compatible nutrients may be combined after proper dilution in the final irrigation water.

Hydroponic Use: Cal-Mag demand varies considerably depending on crop, growth stage, water source and the calcium and magnesium already supplied by the base nutrient program. Account for all nutrient sources when determining the final application rate.

Reverse Osmosis & Soft Water: Low-mineral water may contain little naturally occurring calcium or magnesium. Supplemental Cal-Mag can help provide these essential nutrients as part of a complete feeding program.

Concentrate Compatibility: Do not mix concentrated stock solutions directly with phosphate or sulfate concentrates. Products may be combined after proper dilution in the final irrigation water.

Grower Tip: Maintain healthy roots, adequate moisture, good root-zone aeration and proper environmental conditions to support calcium and magnesium uptake throughout the crop cycle.

Storage & Safety: Store tightly sealed in a cool, dry location. Protect from moisture and humidity. Keep out of reach of children and pets. Not for human or animal consumption.
