It has been watered, you can tell by looking at the photo. Honestly there is no point in saving it. If you do succeed it will take 3-4 weeks to resume normal growth. It would be best to start over if you can get seeds or clones
Yeah sorry to say man but that looks beyond repair. May I ask how this happened? Anyways, good luck with your next grow.
i hadnt added any nutrients at all just the fox farm and the perlite but apparently fox farm has a bunch of nutrients in it=\
