Dude, I don't even know what to say to you. You just called me a prick (I'm female btw...) in the last couple days and asked where the Karma was so you could neg me! Both of which I ignored... I am not here to make friends, or enemies. I am here to grow pot and help people become self-sufficient with their meds and lifestyle.
I told you what is wrong with your plants. You CANNOT give any fertilizer to seedlings at all- not organic, not chem, nothing.

*sigh
Be careful trying to remove soil from roots. If you MUST re-plant seedlings, this is how:
Do you have perlite? Take a party cup. MELT some BIG holes in the bottom EDGE with a lighter. Put some perlite in there, like an inch, then take a large serving spoon and scoop like 4" down and 3" diameter like a big plug of your soil. You can only do this when the seedlings are still tiny. Don't touch the roots. Gently place the whole plug in the cup and backfill around it with plain perlite. Then jiggle it gently to settle, and at this point you may safely flush now that there is good drainage around the harsh or overly-dense soil. Flushing is not very helpful when the soil stays soggy.
You don't need to do that though. It's an emergency measure.

Seedlings, once scorched, sometimes have a tough time bouncing back, but I think yours will grow out of it. I would not stress them more by replanting, but I WOULD drill some holes in the sides of the pots to help the soil drain after all the flushing you are doing. From what I see in the pictures, you now have some new green growth after your flush so just drill the holes, keep your air flow correct, and cross your fingers. Don't overwater, either.
