Your temp is too high. You should be shooting for around 77-80 tops. 85 is gonna give you trouble in flower. Make sure you are running your lights at night so they are that much cooler.

Make sure you are drawing in cool air from outside and venting the warm air outside. Have your fan on the exhaust side of the tube and make sure it is drawing air in and over the bulb and not blowing.
