Ah man sorry to hear about your seeds. Your nutes are out of this world high (I'm using about 1-1.5ml/l when feeding). You might be locked out. What kind of soil are you using? I wouldn't put any more stress on those plants - as in don't top, don't lst at least until they're back on track.
I'd lay off all nutes except for cal-mag and maybe 1ml/l of the micro grow bloom.
What are you thinking about popping in soil next since those autos are gone?
