A shortage of calcium and magnesium (Ca/Mg) in reverse osmosis (RO) water and soft water is a well-known problem. CalMag Pro ensures that a balanced concentration of minerals is available in the water. This is the perfect base to start creating your nutrient water. CalMag Pro is mainly used with RO water and soft water.
CalMag Pro contains the optimal calcium and magnesium ratio to prevent competition between the two nutrients. Some magnesium and calcium fertilisers are not mixable due to sulphates, but CalMag contains both elements in perfect proportion.
