Light stress?

[Mcally]

Help! First grow. Week 11 gorilla glue auto. Everything has been going real well up until last week. Started looking brown on edges and started yellowing. Thought maybe nute burn or ligh
t burn so adjusted both. Kept getting worse so raised light more. Was around 21" over, now around 26". That was this morning. Using Viperspectra 200 watt so not that strong of light. Also 2 other plants starting to show stress. Anything else I can do? Should I trim yellow leaves? Have reduced nutes ( using General Hydroponics trio series with a little molasses last couple weeks) checking ph regularly. The other issue I have been dealing with is heat ( usually high 70's but humidity is usually in 60's) have good airflow but know should be lower. Am outside Atlanta so humidity is issue here. What should I do next?
Thanks for any help.

I think she is telling you she is almost ready for harvest.

It crossed my mind that might be near end of flower except tri"s still pretty clear (I think) Have been checking with 10x mag and still hard to see. Have a 30x ordered and should be here soon so I can really see.
Thanks for input. Any other ideas out there?

She's very near the end of her healthy days they start looking really poorly late in the bloom stage. Yes it's wierd to have that yellowing on top. But for now i would'nt worry about it just get a loupe check for all milky trichomes at best.

Yep I think that I'll just keep checking tri's and get ready to harvest soon. Thanks again for input.

She's just aging gracefully, it can still be 3-4 more weeks.

Should I trim yellow leaves or leave alone?

At this point I'd leave the leaves on till harvest. Your not gonna gain anything by removing them.

I would stop the neuts. and just water. She's just ageing out, leaves do like maple trees in the fall. Turn colors and fall off.

Thanks again for advice. Already started eliminating nutes and keeping eye on ph. Trichomes are still kind of clear but starting to turn. Will wait till start seeing some amber to harvest. Will post some pic's when I do
