Advice on when to harvest

Hey all, this is my first grow and I'm looking for advice on when to harvest. I think I still have some time based on what I've been reading lately, but I'd really appreciate some help!

Week 9 of flower with some white pistils remaining. Mostly cloudy trichomes. I see some amber trichomes on some of the sugar leaves, but very few so far on the bud itself.

So much of what I've read so far says to harvest when the trichomes are milky, but it seems like we're not ready yet based on the number white pistils remaining. I'm also not sure what to look for in terms of swollen calyxes.

3 weeks at least

At this point is your call. I would recommend at least a week, 2 weeks i feel would be best, but if you like that paralyzing couch lock 3 weeks.

Wait until the plant is done pushing white pistils. Once they’re all amber then you’re real close

Thanks for the advice, that all jives with what I was thinking the plants needed.

Do I need to worry about the yellowing fan leaves at this point? That's two plants, and the yellowing seemed to happen pretty quickly on the plant on the right. Here's a picture from 3 days ago, when the fan leaves looked happier.
