Magnesium is essential for chlorophyll production in plants, and in turn chlorophyll is the component in photosynthesis, essentially starting the process through collection of light energy. Mag-Amped is a low molecular weight chelate of magnesium and as such is very easily absorbed by plants.  Mag-Amped is fantastic as a foliar spray, having the same low molecular weight and "clean" properties as CES's other additives. Mag-Amped can also be used in conjunction with CES's two other additives for custom foliar applications.
