Its flowering nearly 70 days.
So, me I'd chop.
Normally most fems take 7 weeks in flowering. Or thereabouts the 56 day mark.
Your trichs are all cloudy. So, it's really just locking in how you like your smoke.
The more amber trichs the harder the smokec will me and vice versa.
Once you have trichs mostly cloudy.. that's THC locked in. And it's all about ripening now to how you like your weed. Me, I like a bit of a harsher smoke on my indicas and I tend to harvest earlier with sativas and day time smokes.
Look up, " the ripening process of weed plants differences, or something along them lines and you'll see what I mean.
As the longer you do leave it, "the trichs to go more amber", will give off different kinds of stones.
Tbh, don't worry too much about it. It's your 1st grow. You'll find your balance.
Autos can be finicky, a few days too long can be the dif in smooth smoke or harsher couch lock bud. Fems, the dif can be 1-2 weeks. But, its flowering 9 wks. So, I'd say she's done
But, she's good to go either way.
