They look HAPPY! Those trichomes are insane, and I can see she’s ripening…
I think as others have said that you need lots of ventilation (as in there is not a ‘too much ventilation’) below the canopy. That is the only real reason you would have trouble from plumage so thick-mold/rot or bugs from stagnant air, as well as circulate O2 & CO2 across those leaves.
I’m insanely jealous that your autos got so big! This is my first year, and mine are too embarrassing to post!
you could probably do 4x 6"fans on high under the canopy and think it is too much… but it wouldn’t be! She knows what she’s doing, and you are trying to fool them into thinking they are really outside…
