Micro Booster 21 Magnesium sulfate 9.5%

•  Micro Booster 21 Mg accelerates photosynthesis in plants and is required to give leaves their green color.

• Without Magnesium, chlorophyll cannot capture sun energy needed for photosynthesis.

• Magnesium deficiency appears on older leaves first as they become yellow between the veins and around the edges.           Purple, red or brown may also appear on the leaves

• Magnesium is also used by plants for the metabolism of carbohydrates and in the cell membrane stabilization.
