I've used Roots Organic and am currently using the GO Box while my batch of Super Soil cooks. I always had problems with plants I have raised w/ Roots Organic soil+nutes around the third week of flower. Just seemed like every plant would go to shit around that time. Recently I have been using a soil named Manna Mix with the GO nutes and things have been going smoothly, but I haven't got those plants to flower yet to see what they will do. Unless you just like mixing up shit for your plants (I did, for a time) I would look into making a super soil if organic is the way you want to stay. There also seem to be some discrepancies as to whether GO nutes are truly organic, but I don't get caught up in all that.
