There's still a bit of clear trichs - I suggest to wait another week or so for all to be cloudy. Really depends what you are looking for.... if wanting more of a sleeper, wait for amber. Many wait for 20ish% amber.. I prefer as close to 100% cloudy as possible.
More airflow, dehumidifier in the room where your tent is. Put on some gloves, turn your fans off, and grab that bud and open it up and look for white webby/dusty areas. If you find this, cut it off and get it out of there. Check the rest of the buds with those dying leaves. Better to catch it early. Hope it's not that though. Good luck
Those are good numbers. I wouldnt be worried about it, most plants that people let flower long enough have color like that. Wouldnt hurt to check though.
