Are All Calcium/Magnesium Supplements Alike?
Calcium/magnesium supplements are commonly prescribed to treat calcium and magnesium deficiencies. Since magnesium is so biologically active, calcium is often used as a buffer. The calcium slows down the uptake of magnesium so excessive magnesium doesn't accumulate in the leaves and become toxic to the plant.
