bob whats up, just like lip said raise your light up, and if you dont have any more room to raise the light, you can start bending your plants. get a fan and try and blow that heat out of the grow area. give your plants superthrive to help with the stress. get those temps down, 85 should be your max. or better yet have your lights come on at night. a lot cooler at night, off during the day. switching will not hurt your plants now.
