Power dead for over 48 hours

Hey ladies and gents,
i have a question about my girl who sadly suffered 50 hours without light or her air pump (I grow DWC)
shes 95% covered and red hairs, and I was thinking to let her go another week or two till my power got shut off...
anyway powers back on today, but shes been without 02 and light for more then two days.
Should I harvest? or turn the lights back on, although that might be to much stress for the girls.

Turn them on and see. Be prepared to chop though. The 2 days of darkness likely set that in motion at the age of the plant.
