my beautiful plant is losing all its fan leaves. 2 weeks left

2 of my plants have really yellowed up in the past 2 days, my most resinous plants leaves have turned completely yellow even the sugarleaves and today is the 2 week mark till harvest.
I use ffof soil and earth juice grow/bloom. I always ph my water to 6.2-6.4 and havnt done anything out of the norm to cause such a drastic change. I dont get it. are they going to die?? heres a picture from a few days ago.

they don't look yellow? did you take the yellow leaves off?

She looks good just relax you're almost done bud

Its normal

no...thats what it looked like before it turned yellow. That big green leaf is all yellow now along with the smaller fan leaves. I checked on them yesterday but never opened the tent, just peered through the flap and didnt see anything unusual. If you guys really want to see it Ill post pics.

with only two weeks left I would just make sure they are flushed and let them ride as is. Be sure to keep an eye on the trichs to pinpoint the perfect harvest day. Happy smokin.
