Your soil may just be a little too ‘hot’ for the seedlings. If you start over use some basic soil mix with less nutes.
on the other hand I’m sure if you just water them with plain water over the next couple weeks they will adjust and start to take off.
With those 2 options in mind, go with the flow, but go ahead and start germinating as a just in case scenario.
So a few weeks ago I tested the soil for NPK. None of it was in excess, was all quite depleted. Indeed I have gone back just to giving them water with bti in it to kill fungus gnats.. hoping they recover soon.
thanks, I may need to start new seeds soon. We shall see.
