Your plants are fine. Theya re in the final stages of bloom and the water uptake has almost ceased as most of the fans and bud leaves are done.

I wouldnt water it anymore and I think you should plan on harvest this week.....

I would also switch these to 10/14 now on the last 5 days.

So if I were you, I would:

Flush (if you need to although you prolly dont)
Take light cycle to 10/14.
Give them their last daylight on Friday....
Harvest on Sunday.

But please post pics daily on the close ups.....these help a bunch

All ssytems appear fine to me and you are simply nearing the pinnacle of your efforts. You COULD pick them now with now loss of yeild.....but I still think another few days of life will help them out.

Nice pics.

Great grow Johhny. Can you believe you made it? Seems so long ago they were but babies huh?
