Ice storm shocked plants

I lost power during an ice storm recently. My plants went without light or heat for two days and it got very cold! I had transplanted about 4 days before and everything was looking good before the power went out. I did my best to keep them warm but couldn't really and I had no way to get them light. When the lights came on I got them back under the light but had trouble getting the room warm again. Growing in coco & perlite - the lowest temp recorded was about 50 F. Air temp was 38 F. They are now up to about 60 and 65 respectively. It's been five days since the light came back on and they still look pretty bad. Leaves curled and not growing. So many things happened I don't know what the cause is or how to fix it. Light, cold, transplant, and transport! Should I just scrap this one and start over. Gave some nutrients today hope that helps. Anybody ever been through something like this?

Wait a while. If they get worse looking, scrap 'em. You may want to start over anyway. The stress will stunt their growth and they may go into flower immediately.

They're not old enough to flower. Will an immature plant that gets 48 hrs of dark come back? Or will it just die?

No. not die from dark. The cold did more damage than the dark. They didn't freeze, so they probably will come back. Did you start from seed? If so, you've already got a fair amount of time invested in them anyway. Just expect a smaller than normal harvest. If they're going to die, you'll know pretty soon.

Yes from seed. F1 of various crosses. Every harvest this year has been messed up somehow. I just want to get through one without a problem!

At least it came early. Imagine if you were three months into the grow and they died.
