That’s not from lighting. Lighting will evenly fade the upper growth closest to the light. Not any lower growth. Heat stress will slow growth but not cause damage. What are the temps?

Usually max of 82.. although it got to 94 1 time when a fan kicked the bucket.. There is another plant different strain that didn’t seem to have any issue.. What else could cause this? Plant wasn’t happy for a while but seems to be bouncing back nicely.. it’s just missing the outside leaves… I was running CO2.. could this be from “acid rain” ? Which can be created from a C02 burner I’ve heard.

No, the issue is root related. Something is stressing the roots out causing twisting leaves with random damage. The plant could also just be ripening as they look pretty mature. The plant should be consuming itself the last few weeks before harvest and drop leaves.

Too much potassium maybe? Without other nutrients? I did give it a banana tea before this started…

I had these same thing a few weeks ago. I figured it was a combination of things. Light damage (i was running about 1200 ppfd). I also over watered (way too high and messed up). Lol

Some leaves never recovered but most did.
