Your plants look ok, however, I think they are not getting enough light. If you have the means, definitely get a 400w. With the fans and setup you have, temps should not be an issue. Move your current light closer and keep with your current schedule. I don't think you are going to satisfied with your yield. Next time, try starting them on an 18/6 or 24 hour light schedule, keeping your light as close as you can without harming them. Good luck.
