First I can relate to the power outages, I've been plagued with similar issues with cycle. My play got an extra 3 hours last night because of a storm. I unplugged the light before it even turned on the wind and lighting was crazy.
Seondlly I wouldn't even start thinking about them being done yet. From these pictures NONE of them are even remotely close. The swelling stage happens at the very end not the middle like this. Currently they are just growing buds and getting bigger.
I would suggest holding off until these plants are actually ripened and mature if you want some really good results. After the pistils are 90ish% red and receeded then it has 2-3 weeks left!!! That is when they swell internally and bulk up. That is when they properly finish maturing.
