m0useanswered grow question 3 years ago Lots of white pistils still. You could let it go for a bit more.
In terms of amber. The trichomes you want to monitor are the ones on the buds themselves not the sugar leaves.
If the buds trichomes are 10-30% then chop it.
The top buds will also ripen first vs the bottom ones. If you have the space you can harvest one part one week and the other part the other week.
Best Of Luck!
