Position your thermometer at canopy level right under your light. You'll see it is hotter than what you have stated, those leaves do not lie.

It’s basicly right underneath the light and above plants. I also have another one believe reading slightly cooler. The thing is it’s been 80f most of the grow and is cooling down here so is only getting slightly cooler each day. But your right the leaves do not lie

Just because the air temp is in range dosnt mean it isnt a heat issue. IR causes surface tempa to rise and dosnt do anything to air temp. It looks like your light has a ton of red and IR.

Air temps at canopy top is 84 to 86
Lazer thermometer sais canopy top is 77. If i lowered the light the air temp will not change much as i have good air circulation but the surfice temps would spike because the plants are closer to the ir.
