Nutrifield Cal-Mag 5L
Calcium Magnesium is a key product within the Nutrifield Plant Health Enhancer Range; formulated to maintain optimal mineral balance, support strong plant structure, and keep your crop performing consistently in high-demand cultivation systems.
Calcium and magnesium deficiencies are among the most common and most damaging issues in hydroponic and coco growing. They creep up gradually, affecting tissue development, photosynthetic performance, and overall plant health, often before visible symptoms appear. Nutrifield Calcium Magnesium is built to prevent that, with a more stable and bioavailable mineral supply than conventional Cal-Mag supplements.
By combining both nitrate and chelated mineral sources, the formulation goes beyond basic Cal-Mag design. Calcium supports cell wall integrity and structural development, maintaining strong plant tissue and healthy new growth throughout the crop cycle. Magnesium sits at the centre of the chlorophyll molecule, directly influencing photosynthetic capacity and energy generation in every leaf.
Chelated calcium and dual-chelated iron maintain nutrient availability across a wider pH range, significantly reducing the risk of lockout and ensuring consistent uptake in hydroponic and coco systems where small fluctuations in availability can measurably impact growth. This is especially important in high-performance environments running intensive feeding programs. The clean, stable formulation supports predictable mixing behaviour and reliable nutrient delivery from the first week to the last. The result is improved mineral stability, consistent nutrient uptake, and a crop that stays healthy and productive rather than fighting deficiencies.
As part of the Nutrifield Plant Health Enhancer Range, Calcium Magnesium keeps the nutritional foundation solid, so the rest of your program can do its job.
