HELP! Yellow leaves in 8th week of flowering!

WHAT IS GOING ON?!

is the ventalation good. the plant looks ready to harvest anyway. not much harvst on your plant but it looks like its going to be a good smoke. NICE

I have an ososolating fan on them for 10 hours a day. The closet door is closed at night. I was expecting them to get bigger... Im using floresants, that probably why they arent producing much. How can i tell if they are ready?

Any other input?

i would put his somewhere between bit over-watering, to Mg or P problem, odd would be some pH issue.
check with this thread https://www.rollitup.org/general-marijuana-growing/1469-marijuana-plant-problems-cures.html

looks like a hotspot from hell.
I would wager light burn or nute burn (pouring nutes directly on leaf).

What is you medium?
Nutes at what strength are you using them?

I use miricle grow i believe a 1/4 teaspoon per half gallon. I used potting mix with styrofoam mixed in. I water about once every few days,a nd i do not put the water directly on the leaves.

Noot burn and looks quite done to me! When you have 85% brown hairs or more it is probably done and not going to get much better and certainly no bigger at this point. Whack 'em, smoke 'em, plant some mo'. Plus, you should back off on nutes altogether a week or so out and just flush with fresh water. This looks like the plant is mature and you kept giving it nutes when it was unable to take more due to maturation. If they are 8 wks, they are done!

DAMN! well should i still flush em with water? i dont want to smoke ferts....

Doubt it will make a noticeable difference now. Looks pretty done and it ain't gonna improve as it done growing, etc. The sugars will start reversing shortly and you will lose THC that way.

what you should do is invest in a maginifying glass..check the tricromes if they are mostly amber..harvest now..if clear wait an flush with water till they turn amber...alsoif they are done i would check out water curing...check the grow faqs ifem you dont know what water curing is...

Ok well i thought id update i just smoked a bowl of some i dried in the microwave and i am BLOWN! I think it is ready so tomaro im gonna harvest the plants! : )
