I have heard of autos never going full cloudy or amber, and I have heard of autos regularly going way longer than what is advertised.
That doesn't really help you since this is your first grow so you have nothing else to reference from experience unfortunately.
It also looks like you removed all of your fan leaves, which would have been my first suggestion: to watch the large lower fan leaves as they progress through senescence (annual plant death) and naturally get fed on by the plant.
From the pics, I would wait and check daily to look for more amber but keep in mind that this thing could just be going long, or may never amber up.
You could also try the following,: turn down your lights just a little over time to send them the signal that winter is coming.
Or you could just reduce the length during lights on by 15 minutes every 2 or 3 days until you get to 11 or 10 hours. It might help trick the plant into wrapping up.
Alternatively, 10 weeks is long...cut the damn thing, dry it correctly, smoke it. If it's too early, cure properly for like 2-3 months, they will amber up. Meanwhile, get started on the next run, maybe with some photoperiods this time. Then you will have a direct comparison on how it is to grow each one and can decide what to do going forward instead of listening to hype or the internet's opinions.
