Looks like nitrogent deficiency or mold to me

You're going to have to give them some kind of nutrients, but don't be scared...just start out at 1/4 strength and see what happens...up it a little if they look better a little at a time....some strains never need full strength nutes, but you're gonna have to give them something besides water and light to grow with.
