maybe some epsom salt?? GLMmm, that would give cal but not the mag as far as I know...
dolomite lime is cal+mag Epsom will give you mag. only thing with lime is it will take a lil bit to take affect. would prob be pointless for you considering you said you will be getting cal/mag in a few days.Mmm, that would give cal but not the mag as far as I know...
