Biomin Magnesium is a fast-acting and fully chelated source of Magnesium.

It can be fed via root but is quicker acting as a foliar spray, especially later in the season. High levels of potassium may aggravate the stress of magnesium deficiency. Magnesium is an important part of chlorophyll and is essential for photosynthesis. Magnesium is highly mobile and if a deficiency is present, the plant will transport it from the older leaves to the younger leaves. Chlorosis, or yellowing between the leaf veins in the older leaves is a good indicator of magnesium deficiency. This product is OMRI-certified organic. 


Apply 1.5-2 oz (3-4 tablespoons) per gallon of water and apply every 2-3 months or as needed.
