I have been around long enough on this forum and have seen tons of threads about what fertilizer to use. The stuff I currently am using has gone up in price... what else is new! I am thinking very seriously of changing over to the MSU formula. The Mg and Ca content of my
tap water is 7 ppm and 28 ppm. These sound like small quantities to me but then what do I know! Should I still use the "regular" formula w/o additional Mg and Ca? I grow lots of paphs, some of which do benefit from additional Mg and Ca. Ray, are you there????? Hello????
