Not sure what is going on. Leaves have brown spots. Grow doc says spider mites but I looked and cannot find any.
Any help would be greatly appreciated

I would start with checking the run off
Numbers. And make adjustments accordingly.

If cant find bugs…little tiny boogers, or webs probably not mites. This will kill if have them and usable to harvest. Looks like calcium spots ftom here but pics can lie. Late flower. Not much recovery coming if a nute prob.

As long as no bugs just keep ph in line. Not a lot left to do. They will finish fine. You are loaded with trichs on the sugar leaves. GREAT edibles shake.

Could it be to much nutrients or to wet just a guess. Almost looks like nutrient burns not sure hopefully they finish strong.
The marks seem to be on the upper leaves more so than lowers.
Lowers seem healthy and mark free.
Could possibly be your light intensity.

They have definitely gotten worse. That appears to be light bleaching . Early pics looked like spider mites but this looks like light burn. May want to decrease light power or raise it a bit. Or is that DE or something you put on them?
Great observation. After looking at pictures and my notes it seems this happened shortly after I tweaked the lights. I have decreased intensity. Will I be able to see if the problem is solved. I will check DLI at top bud when light cycles on. Thank you for your advice

Welcome. You will only see improvement in new growth, damage is done, those won’t get better but will still photosynthesize light. Just not as efficient as healthy leaves.
