Calmag

BioBizz CalMag is an organic, certified calcium and magnesium supplement designed for cannabis growers working with soft tap water, reverse osmosis water, or any situation where Ca/Mg deficiencies are likely to appear. Calcium and magnesium are essential secondary nutrients — calcium supports cell wall integrity and new growth, while magnesium is the central atom of chlorophyll and critical for photosynthesis.

Developed for both professional and hobbyist growers, BioBizz CalMag uses naturally derived ingredients that don't disrupt the BioBizz organic nutrient program or the soil food web. It's compatible with all BioBizz products and designed to integrate cleanly into existing feed schedules without altering pH or EC dramatically.

Use CalMag from early vegetative growth through mid-flower, or apply reactively when you spot yellowing between leaf veins (magnesium deficiency) or dying leaf tips (calcium deficiency). It works in soil, coco, and hydro. Coco growers in particular tend to need supplemental Ca/Mg due to coco's natural cation exchange properties, and BioBizz CalMag covers this gap without synthetic chelates.
