Spyder7answered grow question 4 years ago I wouldn't worry about it that far into flower. The only problem I had from a longer outage was the humidity that built up in the sealed tent: 80% peak during about week 5 (2 weeks into flower) but it didn't hurt the plant. I learned for next time it happens (and it will: I get a few outages a year from severe weather) I'll open the tent so the plant can breathe but I think you're fine.
Maybe consider using something bud safe to prevent mold, but that would be the only fear and you can prevent that.
