http://www.epsomsaltcouncil.org/plants.htm sez Epsom Salt Crystals help your regular plant food work better. Most all-purpose plant foods do not contain the secondary nutrients magnesium and sulfur which are essential to plant health. Epsom Salt Crystals provide these vital nutrients to help prevent loss of green color, yellowing leaves. In additional, Epsom Salt Crystals make the primary nutrients in most plant foods (nitrogen, phosphorus, potassium) more effective. Professional growers rely on the elements in Epsom Salt Crystals for better yields and healthier crops Again, the above is an industry council statement, but it's rings true. Calcium and magnesium are close chemically, and magnesium may very well promote the availability or absorption of other nutrients. My .02--I'm not an expert but wanted to point out that Epsom salt doesn't actually have phosphorus in it.
