You can think of the leaf, like your arm. In the blazing sun, you sweat, and that sweat creates tiny microscopic water molecules that form on your skin, till the Air drys it or is whip'ed off. But till it is dissipated or removed, its like a magnifying glass. It will burn the surface. as to why a fan is just as important as an AC for your area.
But what ive been experimenting with, is intermittence of intensity/rest periods of photons. Blast with light, then let it recoup for a bit, and repeat. Since ive been doing this, it has been by-far my best growth to date. As far as no burnt leaves, or old leaf syndrome, that looks like leather. At least i think it has something to do with it, lol.. I think i also got a few differnet things in order, like PH, nutes and such,lol. WHoooooknows,
Down the line, id like to set up muliple grow areas, to test certain things as far as stem to DLI ratio, and photon rest periods.
