PhotoMag™ is a synergistic blend of minerals designed to provide the key nutrients used in photosynthesis and protein synthesis. PhotoMag™contains magnesium to provide the building block of chlorophyll and sulfur, boron, cobalt and molybdenum to aid in the production of proteins. PhotoMag™ helps increase photosynthetic efficiency, it promotes better mineral mobility from soil reserves, and facilitates nitrate metabolism within the plant.
