NL "Auto," Day 76, about to enter Week 6 flowering. How far along until harvest?

Title. Been growing this since September with Seedsman NL "Auto." I put quotations because my first harvest had to be trashed after it refused to flower even into Week 11, and this one didn't flower until I flipped 12-12. Could be photoperiod, but lots of people have put similar complaints on Seedsman's recent NL Autos. Something to be wary of if you're thinking of buying that particular strain.

Anywho, this is my first time getting to flower. How are these looking, and when do you think they'll be ready? I'm shooting for December 20-24 as a chop date, which is 3-3.5 weeks away. Might not be able to do later due to life conditions.

(Sorry for quality of pics; haven't been able to get good pics since she's grown so wide in the tent I can't remove her).

Looking at that pic, you still have a few weeks left.

Updating this, since it's been about 2.5 weeks. I'll have to chop by next Sunday due to family coming over. Would peg her as in the harvest window based on trichromes, yellowing leaves, pistils browning, caylx's swelling, and samples.

Think I'll be losing much if I cut her next week? Or is she just about there?
