How long until I Start The Cut??

So I am Week 9 of flowering and i am thinking these babies are looking real good! I could use some more advise from very experienced outdoor growers.. I have been told with a flushing agent such as flawless flush that i only need about a week of consistent flushing before i start to cut? When i start to cut, do i work from top down, bottom up, or whatever looks furthest along? I am seeing some amber trichomes on some buds, some milky on others, and some clear on some of them also???? I have added some photos for you guys to check out. thanks for all the heads up. Can't wait, gonna be a good harvest I think.

Ps: should I have a very small space fan in my dry closet to circulate air??

i'd go another 7-10 days, and ditch the flushing, it's not needed.
Personally I don't like a fan blowing on the drying nugs, as long as it's nt humid outside I like to just hang them with a ventilated room, but no fan.
You can use a fan if you want, but it makes the nugs dry too fast, in my experience.

water the plant like you normally would, and don't take advice from whoever sold you the flush
