David, first off how are you? Hope all is well.

Re: The plants - it seriously looks like some sort of nutrient lock or something, flush then re-pot.

Here's how I start mine. (I'm not saying there is a right or wrong way but this is what works for me).
For four plants and a medium yeild.

Soak and germinate seeds as usual (paper towel method).
The pots you have are fine.
I then get 3-4 cheap growbags, cut them all open in the bath and thoroughly mix in about 20-30% pearlite, that's it - no water no nutes, nothing (there's enough nutes in the grow bag crap to keep 'em going for a while).
Put about 2" of small stones (about ½-1" in diameter) in the bottom of the pots which have holes drilled all over the bottom. Fill with the mix DON'T PACK DOWN - put the mix in lightly (sprinkle it in with your hands).
Then seeds into pots (you know the lighting requirements).
DON'T WATER right away!
That's it - and don't feed at all for the first three to four weeks.

You want a plant looking like this after 2-3 weeks (see the soil).

Glad to see you're still around!
