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.
Add a maximum of 1 ml CalMag Pro per 1 litre of water (1:1000). Use this solution each time the plants are irrigated.
