Your doing a good job homie. Unfortunatly the top bud is suffering from heat stress. I cant even see the bud that clearly but you can tell by looking at the associated leaves. The tips look a little cooked and even the middle of the leaves look a little fried. The fan should help out a great deal - you will be suprised at the difference it makes. Also - GH makes a foliar spray called "chi" that might help keep the plants a bit shorter and more heat resistant. I have not used chi however - you might want to search the posts and see if anyone else had great results with it. Keep up the good work!
