Dude...not looking so good at all. Don't use both or either one of those soil types. Scott's is alright, but no MG. Dont' grow in a garbage can, get a grow tent instead. I have been there and I will give you some advice. Stop wasting your money and get some real growing supplies. Your temps are too high and your humidity is too low. My plants are a month old and about 8" tall and bushy as hell. I think they would a be little better looking but about two weeks ago I over feed them a little. Also don't use advanced nutes. These is a real controversy but anvanced is such a rip off. Buy cheaper nutes and with the money you save buy the good grow supplies.
