Hey,
just knowing your in week 8 id say you have atleast few days more. The trichomes you can see only the top i guess are just reflecting some light, Trichomes you can see from the side look more glassy than milky.
A good other indicator is the pistils, yes. When they curl in and are mostly orange/brown your plant is definetly in maturing and not pushing budsize anymore, otherwise you would have white fresh pistils.
You definetly in the last 2 week range then and i suppose thats where you are, but i would give them atleast 1 more week.
Dont hesitate and trust your eyes mate, you will see when pistills turn amber/get more milky.
Happy Growing and harvest, you got this!👍
