Red hairs/ clear triches

Quick question. I have some girls going that are on dy 63 on a 7 to 8 wk strain. About half way thru, we had bad ice storm lost power for 4 dys. Im running flood n drain and was able to keep girls going by hand watering and sunlight thru windows. The light schedule did get changed yby around 4 hrs. Ive run these strains for a while now, and usually when the hairs turn orange or red theyre done.
What im wondering is, could the light change and cold temps could have changed the way they finish out?
Usually they pack on theyre weight at wk 6, but are just now in the last cpl dys starting to really swell up.
Kind of worried bout running too long due to earlier stress, and would hate for them to hermie.
Any insight or ideas will be appreciated. Thanx in advance and sorry for thread lay out. Posting from phone and it is not wanting to cooperate.

Phenos are different. If it's starting to swell I wouldn't worry. 4 hours will cause stress but not as much as you're worrying about. Chill and let them finish.

I guess that's all i can do is let them run. These are all cuttings from mother ive had for a while.
If it was just the light change i wouldnt have tjought twice about it. But it was 4 dys of screwed up lighting and real cold.
Thanx for the reply.
