looks like over watering to me might cut back some

Your new growth is straight up and the top leaves under it are folding themselves in half in an attempt to not expose surface area to your light because it's to close. Your causing heat stress. Move the light 18-24 inches away from the tops....

yaeh, i think the heat stress is the problem too.

cheers guys ill move the light asap. let you know if it perks up.
