Ah! I see on the GC under the 96s the same kind of damage I have on mine right now - now I know why you suspect lighting, post-defol, being the cause in my case.

Fair enough - wasn't trying to take a dig at you or anything (to be clear) - I just figured it was experience talking
Oh no, didn’t take it that way. Just trying to be specific about likely cause...

pretty common issue for me, at high intensity/temp and thick foliage...signal that needs defol...as i hang on for a few days supporting start of stretch...

Would that be from the shade of the leaves causing enough temperature differentiation for condensation to form, or is something else causing the condensation?

Leaves covering each other, shaded leaf cooler than air temp, moisture condenses on cool leaf, wet leaf moves into light somehow, light gets magnified by water, leaf burns like when you were a kid with a magnifying glass...

Nothin to write home about...?yet?...but the girls are starting to stretch a few mm...and are slurping nutes. Seem to be tolerating uv well.

Raised the qbs and uvs...will bring nutes back up to 1.6ish ec tomorrow.

Changed out co2 tanks, first 100lbs lasted 10 days...expect the new ones to last a little longer, since i closed one of the two open vents on each tent, as plants generate their own humidity...

Will bump uv exposure another 1.5 hrs on Tuesday; taking total exposure up to 1/2 hr for every other hour during lightson.

Probably start next round of defol on sunday...to get some air and light down thru top of canopy.

Lightson 12hrs, no supplementals except uva/b, ppfd ~1050
Air temp 86F, rh 60% avg
Water trmp 68F, pH 6.1
CO2 1500 ppm, lightson only

The only difference i’m seeing so far:

6x96 @ 943w
