#5 Magnesium Sulphate MgSO₄

Hydrotech’s Six Pack Magnesium Sulphate is a combination of magnesium and sulfur. Both nutrients are beneficial for plant health; magnesium is involved in photosynthesis, deficiency of this nutrient ultimately affects leaf color. Sulfur activates plant enzyme systems, a deficiency of sulfur results in growth and color changes. Observation of plant leaves provides information needed to diagnose nutrient deficiencies. Hydrotech has created this unique mixture to provide vital nutrients to help prevent loss of green color and yellowing of leaves.
