If they went droopy a bit after the lights going off, then I'd say it's just the plant storing energy.... No need for the leaves to be reaching for light when it isn't there....just my opinion though....

As for the bottom crispy leaves, cut 'em off, let 'em fall, it's up to you.... It's nothing to be worried about....as long as the whole plant doesn't follow....and probably won't....

How about a full plant pic???
