Mmm, you might consider using powdered Dolomite lime as a liming agent then. Dolomite is Mg heavy! I avoid it like the plague, for that reason. I get plenty of Mg in my soil builds - From other amendments (in total). AGREED! I did use 50/50 dolomite/oyster shell and it was fine until about 4 weeks into bloom before I started to get Mg def (clearly)
