Is it bad to let northern lights flower past 9 weeks?
I have a plant about to finish its 9th week of flowering. It would be great if I could let it go another two weeks and then harvest and let it dry while gone for a week...would that be a bad idea or think it would be fine.

It’s up to the trichomes. There is only a small window of time to harvest. They can’t be left to get over ripe.
I agree with @Green thumb ... If you let it flower for longer than it needs, the trichomes degrade from THC to CBN (cloudy to amber).
