Description
BioBizz Calmag is a fully organic calcium and magnesium supplement designed to prevent and correct CalMag deficiencies when growing with soft water or reverse osmosis (RO) water.
BioBizz nutrients are formulated for use with medium-hard water. If your water contains low levels of calcium and magnesium, plants can quickly develop deficiencies that impact growth, leaf colour and overall plant health. BioBizz Calmag restores the correct mineral balance so plants can grow at their full potential.
- Dilution / Dose
- Prevention: 0.5–1ml/L (hydro/coco) or 0.3–0.8ml/L (soil). Correction: up to 1.4ml/L (hydro/coco) or 1.2ml/L (soil).
- When To Use
- Whenever growing with soft or reverse-osmosis water, and during heavy bloom or PK-booster feeding when calcium and magnesium become less available.
- Substrate Fit
- Soil, coco and hydro.
- Grower Notes
- Fully organic. Calcium strengthens cell walls and disease resistance; magnesium drives chlorophyll production and light absorption.

Why Calcium & Magnesium Matter
Calcium strengthens plant cell walls and helps plants resist stress and disease.
Magnesium is a key component of chlorophyll, allowing plants to efficiently absorb light and produce energy.
During heavy feeding, particularly when using bloom nutrients or PK boosters, calcium and magnesium can become less available to plants. Adding BioBizz Calmag ensures plants continue to receive the minerals they need throughout the grow cycle.

Growing With BioBizz
BioBizz nutrients are fully organic and designed to work with beneficial microbes in the root zone. When using tap water, chlorine and chloramine can harm these microbes.
For best results we recommend conditioning your water with Ecothrive Neutralise and boosting microbial life with Ecothrive Biosys throughout the grow cycle.
