20-7-20

High Mag Formula

20-7-20 Formula is a balanced blend that offers higher levels of Magnesium to offset deficiencies in the growing medium. Magnesium benefits the plants by allowing better uptake of Nitrogen and Phosphorous. It is not, however, intended for use in large area where Magnesium levels are too low.
