in a greenhouse when it's 35+ outside in desert heat? doubt that.
What desert are you in? I'm in the Mojave Desert and I grow in an un air conditioned house. I shut down my lights when my canopy temps reach 105 and right now my canopy won't be below 96 until likely October.

Anyway I'm sure you know better. Then again I'm not the one worrying I have PM. So there is that.

Not pm. Pm white spots, ld be looking at insects, holes are irradic. That something eating at them. Just my opinion, been fighting pm for over a month, scars leaves once gone, always dots. Pic is pm dammage and DE spray residual. I spray labs and de mix to kill pm. Not best example or pic, but have almost irradicated so this is it. Will leave thumbnail for op. Not trying to steal thread but not pm.

It's 33 to 35C here these days and my greenhouse is a lot higher but my plants do great. No foliar spray needed. Just a fan.
that's dangerous, I shaded the heck out of my greenhouse for that exact reason. Are you using an LED at night to make up for lost daylight or just letting nature take it course?

I should say semi desert - surrounded by fires. Appreciate you sharing thought for real, I have lots of learning a head of me when it comes to environment outside.

that's a hell of a stem! Glad you don't think it's PM, ya the holes..also some weird genetics from CK 3 leaves and even 7 leaves..

I believe I fucked up by not leaving nay windows open during the night for fresh air, as I wanted to keep the greenhouse as warm as possible it drops low some nights.

I've been reading more and more of experienced growers just not doing/needing IPM foliar sprays. I'm currently on my 3rd consecutive run w/o any and so far so good. As long as i don't get lazy. . ...
I think you're right and that has been my experience. I only spray when I absolutely have to. I desperately try for root drench solutions for most things.
