Im have and I already used less than recomended generic dolomite lime this time and added solution grade gypsum powder by the cup plus per CF of base soil. The base soil is bagged and has some lime in it per their advertising. I dont want to add too much lime. Its a new mix recommended with lime but I am not sure if I should add as much the mix calls for. I have no way for sure of knowing but Im leery of adding to much Mg. Of course I could be off my rocker and completely wrong.
Im no expert but I always am leery of adding to much lime but not of adding a lot of gypsum.
Im using a variation of it now for the first time for some plants in small bags starting flower and they do look fine. I added about half the dolomite
lime recommended plus gypsum at twice the level recommended for dolomite lime.
