I'd cut the wilted leaves off. Not sure when you watered, but leave out any moisture for the next couple of days (like has been mentioned) and watch what the plant tells you. It'll be fairly apparent. I ran into this issue with my tomato seedlings recently as well. Used a medium I was unfamiliar with (seed starter) instead of a well draining mix of Promix. And I've been doing tomato's for over 20 years so don't worry....you'll get the jist of it. Plants don't want as much water as many think they do. Just giving an example of what can happen even if you have experience.
