NPK RAW Calcium/Mag

NPK RAW Calcium/Mag delivers 15% Calcium and 3% Magnesium to plants in a fully water-soluble form. This optimized blend supports strong cell structure, nutrient mobility, and photosynthesis without leaving salt buildup in the growing media.

Calcium and magnesium deficiencies are among the most common issues in intensive cultivation—and they often appear together. RAW Calcium/Mag solves this with a precise formulation of calcium nitrate and magnesium sulfate.

• Calcium for Structure: Strengthens cell walls, promotes root growth, and helps prevent issues like tip burn and blossom end rot.
• Magnesium for Energy: Central to chlorophyll, driving photosynthesis and ensuring efficient nutrient metabolism.
• An Added Edge: Because this formula uses calcium nitrate, plants also receive a touch of clean nitrate nitrogen. This small addition improves uptake synergy without overloading the crop. It’s safe through bloom and won’t trigger unwanted stretch.
• Optimized Balance: The 15:3 ratio of calcium to magnesium ensures both nutrients are delivered harmoniously, preventing lockouts and maintaining a clean, efficient root zone.

RAW Calcium/Mag is ideal for preventing and correcting deficiencies, fine-tuning nutrient recipes, and supporting high-quality growth and production. Its concentrated, 100% soluble form means a little goes a long way in soil, hydroponics or fertigation.
