The leaves are essential for sugar etc. production, and your plant will suffer if you remove them. If you do, cut them right where they come out of the main stalk so that there are no nubs sticking up to attract pests or disease, or shirtsleeves.
85 degrees is not a huge deal, as some people have grows above 90 and do OK. It is somewhat of a deal though. You need to keep the surface of your leaves below 80, and that means the air around them should be no more than 83. The best way to tell is to get a laser thermometer which actually measures the leaf temp. At 80 transpiration (and therefore growth) slows greatly or can even stop altogether.
PPM max?
cuttings - 50
seedlings - 300
young adults - 800
adults - 1400
middle of flowering - 1700
2nd to last week - 1400
last week - 50
This is based on the U.S., or 500 scale. These are maximum averages. Each variety is different. The best way to tell how much your plants can handle is to watch carefully as you increase gradually about 100 each feeding until you notice the first signs of stress, then back off a notch.
Hope that helps.
