This Cal-Mag Special formula is probably very close to being the perfect fertilizer all in one bag. It contains most of the major, secondary and minor elements almost any crop would need. NPK, Calcium, Magnesium, Six trace elements and a very high ratio of nitrogen in nitrate form. The calcium to magnesium ratio is 4 to 1 and while slightly on the acid side, this formula should have minimal impact on media pH.
