It appears as though its normal drawing of nutes from the fan leaves.

Worry not.

Losing some of those leaves will help the light get on the buds a bit more as well.

On the real yellow ones, you can go ahead and pinch those off.

Not cut.

I like to pinch anything I am going to throw away as it may help seal the wound faster and prevent mold or infection. Once those stems turn purple / red like that, they're done.

But again it looks normal and btw....those are nice buds....if you are only 65% thru flower at 6 weeks, you gonna really love them at week 9

Looking super nice grow.

Keep me us updated please. I wanna see these grow.
