Cal-Mag® Plus is a specialised calcium, magnesium & iron plant supplement designed to compensate for deficiencies in some commercial and hydroponic nutrient programmes. Cal-Mag Plus also compensates for the natural calcium draw of coco coir fibre.

Cal-Mag® Plus provides a precise balance and optimal ratios of the calcium, magnesium, and iron that are critical throughout all stages of growth, especially in heavily fruiting plants and fast blooming annuals. Cal-Mag Plus is fortified with a proprietary blend of select trace minerals to help maximise yields in fruiting and flowering plant varieties, prevent blossom end rot in tomatoes and peppers and reduce tip burn in lettuce. When used in combination with nutrient solutions Cal-Mag Plus functions as a catalyst to increase the uptake of essential minerals.
