I wouldn't use miracle grow anything. One common thread amongst the experienced growers(which I don't consider myself one)has always been to stay away from miracle grow products. Still, I can't say that's what's causing the yellowing.
Also, I'd get rid of the tinfoil when you make your next growbox and use flat white paint or mylar.
