Can someone tell me what happened to my plant? It is very early on and i want to know if it will still produce a good amount of weed, if any at all. If you take a look, one of the first two leaves stopped growing and turned a purplish. The next two leaves that are coming in are growing and look fine. Will that one leaf hold back the plant from growing? Will it eventually straighten out?

In that drawer the temperature is about 80 - 85. The lamp is a flourescent 120 volt growlight.
