Hey guys. I started my outdoor grow about three weeks ago. For two of my plants I used MG organic potting mix or something like that and the other two I used scotts moisture control potting mix. The two in Scotts grew extremely fast and vigorous with large healthy leaves. I had to chop the two MG plants today cause they simply stopped growing after they grew 3 sets of yellowish baby leaves. EVERYTHING was the same. The same amount of light, the same size pots, the same location. I strongly recommend that if you can only buy cheap soil, buy Scotts Moisture Control potting mix. Or anything that isn't miracle grow. I messed my first grow up by using MG nutes. The Scotts soil says it has 3 months of time release nutrients and already has perilite in it. It was like 6 bucks for a big bag at walmart. Hope this helped
