Description

A precise cal-mag correction, not a guess

RAW Calcium Magnesium delivers 15% calcium and 3% magnesium in a fully water-soluble form, built from a precise combination of calcium nitrate and magnesium sulfate. Calcium and magnesium deficiencies are among the most common lockout issues in fast-growing, high-EC feeding programmes, particularly in coco and RO-fed hydro systems where the source water carries little of either mineral naturally.

Because it is a straight two-element product, growers can dose it independently of the base feed to correct a deficiency precisely rather than switching an entire feed line to chase one issue.

Key Benefits

  • 15% calcium, 3% magnesium, fully water-soluble
  • Corrects cal-mag deficiencies common in coco and RO-fed systems
  • Sourced from calcium nitrate and magnesium sulfate
  • Doses independently of the main base feed
  • Suits soil, coco and hydroponic systems

How to Use

  • Add to the reservoir at every feed where the base or source water runs low in calcium or magnesium
  • Dissolve fully before combining with other nutrients

Technical Specifications

  • Guaranteed analysis: 15% Calcium, 3% Magnesium
  • Source: calcium nitrate, magnesium sulfate
  • Format: soluble powder
