Yellow Leaves 9 weeks in flowering - Pics

[Musiclvr]

Hey guys, sorry for the repost. I have three plants that should be getting close, they have an estimated 8 weeks flowering and about to enter week 10 without a single amber trich. My concern is the yellowing leaves, they have yellowed all the way up to the main stem. Literally NO large fan leaves are still present, only the smaller ones. There are leaves that are falling off that actually have trich's on them.

Strain: AK47/WhiteWidow
Soil: Fox Farm Ocean
Light: 1000w HPS

Grown from seed, and Canna nutes with last week only water. I would say half cloudy/clear and it appears like trichs are still developing. This is my first grow and there was a a couple of days the room got up to the upper 90's and a few nights in got down to the mid 50's. So I may have stressed the plant out. Anyway, any feedback would help. Just not sure if I should chop, or wait.

first off, nice job for your first time. looks better than my first grow.

Anytime your fan leaves begin to yellow like that you run the risk of mold starting at the exact point where the leaf connects to the plant.
If you can tug on the fan leaf and it comes off thats not really a good thing. its going to happen throughout the later weeks of flowering, but be sure to do the tug test on yellow leaves.
I personally would chop it. 10 weeks is plenty. plus with leaves that yellow and buds that big you dont want to fight mold. AK-47 is my favorite strain and I have grown it many times so this advice is from direct experience and not based on hunches.

Hope this helps...

your plant is fine a lot of plants yellow at the very end taking in the last amount of its nutrients plan to cut it down in the next day or so and all will be fine.
