This I agree with 100%. I did a grow in MG soil and my plant kept a dark green to it through out almost complete grow(Nirtgen lvl was alway high). I feed it every 3-4 waterings into flower only! Still kept its dark green. Even at the end into harvest. I flushed for 2 weeks to try and get nutes out, with little results! This was a trial and error for me. I have since moved on to A Top Feed Hydro set up! Now the only nutes my babies get are the one I give! If I ever chose to do a soil grow again. I will NOT use MG. A heavy nuted soil is hard to dial in on nutes since they are always present in the soil. Not good for harvesting! This is only my 2cents and opinion!
