First Grow

I'm about 4 weeks in. I'm going to start flowering next week. I got 4 grand daddy purples in a 2x6 box w/ a 600 watt hps. I've had a lil' trouble with heat (my air conditioner broke and it went to 85 for a few days), but i'm keeping them under 80degrees now. I pruned all the yellow leaves and topped them last week. Let me know what you think:

They're about 12 inches tall now

yes there a bit heat stress. i run high 80's low 90's. if you can get good amount of fresh air and have good air flow that will be better. they look good but even better when you fix the heat problem. keep it up and good luck. welcome to the site.
