My original grow started off using MG with time release nutes - Started off well, then when they were vegging I actually added some straight N (22.0.0) and ended up frying them. I can testify that I've grown cannabis in MG before, but never added anything until flowering, at which point I used MG bloom booster -

So unless your about 4-5 weeks into flowering, don't add any more nutes (from my experience)
