What might this be? Pics attached.

Almost day 21 of flower. Yellowing leaves started more at the bottom and are now getting more to the top. They are also easy to pluck off and if left will wilt and fall off themselves.

I would say that roughly 1/5 of the leaves are now yellow. The ph of the soul pot is roughly 6.4.

I use Florflex nutrients and are following their schedule. I am not sure what is going on to be honest.

Please help.

I had a similar problem late in flower which i could never figure out.
My yields were fine though, and i was guessing it was phosphorous deficiency.

I'll be following this to see if anyone can solve this.

So I put this in the general thread and it got way more attention.
