When to finish/flush? Late flower - Harvest Questions

Normally you want to check your Buds Tricomes with a Jewelers Loop or equivalent. Your looking for about 20-30% of your tricomes to be amber in color.This is when You should harvest! When you start seeing your first amber tricomes is when I would begin your flush and only water with Ph balanced water. Check out my first grow if you have the time! cheers and happy growing!

oh, and flushing isn't neccessary unless you've been killing it with nutes.

get a 30x jeweler's loup or 60x? think they advertise as 60x but 30x is all you can focus. the little currency ones.. same thing.. find a cheapy, unless you want to take macro-pics. (really should call them micro pics, ffs) anyway, use that to judge trichome color -- clousy is optimal, amber is only degrading into less psychoactive components. and glassy is immature. google image is your friend here. and there are tons of places to read up on "when" you should harvest... regardless, this will get you in that 2-3 day window and you can choose what you like.
