Most "new" growers have problems with MG because it is notorious for burning plants if followed by box instructions and not given in a lower amount (ex. 1/4 recommended amount). This is simply what i have read on this forum in many threads. I say if you have MG nutes down pat then the more power to you :thumbsup:. For the original poster there is tons of threads on here about soil and different companies. Pick one and keep us updated :smokin:
