super thrive problem please help

Ok so I already know what the problem is but I need some help fixing it, so I gave my plants that are sprouting and a clone the super thrive I must have mixed too much in and now they are dieing if too much nutrients, anybody have any help with this other than flushing??? Any help would be much appreciated

that stuff is potent with the little ones. i would just give them ro or 24 hour sit water and raise the lights...hope for the best...im sure it will work out unless they are super fried hard to tell without pics
