Monkey Nutrients - Monkey Mag Cal Overview. Mag Cal is a Magnesium and Calcium supplement; two essential macro nutrients like NPK although required in smaller quantities so referred to as “secondary nutrients”. Magnesium and calcium supplements are extremely Important for growers in soft water areas, using reverse osmosis filtration or coco based mediums. Calciums primary role in plant growth is to provide strength to cell walls, in the same way we need calcium for our bones. Magnesium is an essential component in chlorophyll and so vital for photosynthesis. Along side these secondary nutrients there is also a blend of trace micro elements for any potential deficiencies. How it works. Magnesium sits at the very centre of a chlorophyll molecule surrounded by 4 nitrogen atoms. Without it , plants could not photosynthesise. It allows plants to create energy from light and is responsible for its green colour. Magnesium also plays roles in enzyme activation of carbohydrate metabolism and translocation. Calcium provides strength and rigidity to cell wall formation in shoots and roots. It also plays an important role in cell membrane permeability. enzyme activation by Calcium further promotes cell growth. A lack of calcium shows serious growth inhibitions in plant development.
