to much nutes for young plants help

So i started some babies about two and half weeks ago and i am a new grower inside. i'm doing liquid nutes and did realize the concentration of the stuff and now there trying to die. i fushed them well and was going to transfer them to a bigger pot but i thought they being stressed already it may kill them. Any thoughts that may help will be three weeks old on 4/1.

...post up some pictures.

peace, bozo
