Botanicare Cal-Mag Plus

Cal-Mag Plus provides a precise balance and optimal ratios of calcium, magnesium, and iron that are critical throughout all stages of growth and helps maximize yields in fruiting and flowering plant varieties. This highly fortified plant supplement works great on heavily fruiting plants and fast blooming annuals as well as preventing blossom end rot in tomatoes and peppers, and reduce tip burn in lettuce.  When mixed into a nutrient solution, Cal-Mag Plus acts as a catalyst to increase the uptake of essential minerals.
