from your picture it looks like the portable air conditioner is blasting away on your girls. I think that is the main the problem and if your temps stay at 90' during the whole flowering you are lucky they look so as good as they do. The portable ac will also lower humidity levels as well. Check the roots as well. Soggy plants sag.
