When to start flush

Your still a way of yet. Aim for the pistils turning brown, when you have 80-90% brown hairs your good to flush.

yes for me it is now that I start to fluching my plants after the weeks given by the seed supplier should not be taken as they say because the weeks depend on several things in fact me I look at the trichomes and when they are at 20% brown I harvest

Definitely don’t recommend flushing at this point. Let her go.. those auto flowering times can be much longer. The breeder gives the best possible flowering time to entice ppl to buy in my opinion. She really needs to pack on more weight at this point and starting to flush would starve her of nutrients that will get you more bud and better bud. I would wait at the least 10 days before even considering flushing. More likely 15-20 days

Only going by the pictures. I see your plant is still immature and also see clear trichomes. Looks like you still have a good 2 1/2-3 weeks to go. Then recheck the trichomes. That might be a better time to flush.
