PuurCalMag is an OMRI-certified organic calcium and magnesium supplement chelated with organic acetic acid for fast absorption. The formula prevents the most common nutrient deficiencies in coco coir, RO water systems, and LED grows while maintaining full organic compliance. Essential for any PuurOrganics feeding program.
Calcium and magnesium deficiencies plague organic growers using modern cultivation methods. Coco coir strips calcium from nutrient solutions. RO water lacks natural mineral content. LED lighting increases Cal-Mag demand. PuurCalMag solves these problems with organically chelated minerals that remain plant-available across all pH ranges.
Key Benefits
- Organic acetic acid chelation delivers fast calcium and magnesium absorption
- Prevents brown spots, interveinal yellowing, and weak cell walls
- Sourced from mined limestone (calcium) and deep-earth brine (magnesium)
- OMRI Listed for certified organic production
Ideal For
Organic growers using coco coir, RO water, or LED lighting where calcium and magnesium deficiencies commonly occur. Apply at every feeding from seedling through harvest.
Best Results In
Soil, living soil, and coco coir. While fully soluble and technically hydro-compatible, organic nutrients in DWC/RDWC require more attention to reservoir management and pH stability. New hydro growers should consider the Classic 3-Part system.
