If it is not from heat stress, it is the leaf transpiring and photosynthesizing at its max capacity, lots of transpiration, healthy vacuum. Not a bad thing, unless your medium gets drier than ambiant air, then your plants get sucked dry and the pours close.I'm honestly not sure. The canopy wasn't warm at all from what I could feel, but others have suggested it was heat stress. So I'm not sure if it was just from late flower, or if it was heat stress.
