i hope your grow box is not still 92 degrees because that is way too hot. you will seriously hurt your harvest with such hot temps, you might even make a hermie. cool it down, get a cool tube or air cooled hood pronto.

as for the stretch, it might just be the flower stretch. plants can double or triple in size during flower depending on the strain.

it's hard to tell from the pics but they look healthy enough. if they start to get too tall just tie them down some or put a screen above them to keep them out of the light.
