Help! Problems w/ young plants (with pictures)

My plants are about 2.5 weeks old and have slowed in growth, are wilting, and have yellowed severely(pictures below). I have been fertilizing with Miracle Gro 18-18-20 but the problem persists... If anyone has any clue what could be the problem I would greatly appreciate any feedback. Thanks guys!

over nuting these are just babies and need no nutes yet, dont over water em either.
