Description
With Dutch Pro Calmag, you can rest assured that your plants will get the calcium and magnesium they need, Dutch pro has developed its own revolutionary calcium/magnesium with added nitrogen to counteract the plants' increased demand for nitrogen.
The hardness of water is affected by the amount of calcium and magnesium present in the water supply. Calcium deficiency symptoms are subtle at first, but they manifest in brittle stems, dark leaves, and poor growth. Older leaves that are magnesium deficient will turn yellow between the veins and/or have rusty brown patches.
Dutch Pro Calmag is suitable for every substrate and every irrigation system.
