kmkblazeallday Reviewed by kmkblazeallday on . When to start using ferts? It's been about two weeks since I planted them, and on one I'm noticing a slight yellowing on the tips of the leaves on one of them...it looks like lack of nitrogen, but it doesn't seem likely to me that this would be happening this early..can someone enlighten me?:stoned: Rating: 5
