Transplant to soil?

it looks like way to much water. Did you plant it in 100% Peat moss? if so it retains way too much water and have a way too low PH. Not sure how to save it, maybe try and remove it carefully with the from the medium and transplant it in to some propper aerated seedling soil

I would move them immediately myself! You will end up with the entire seedling damping off and dying if you do not... especially in seedling stage! They need a cycle of dry/moist/dry/moist .... not wet, wet, wet... So transplant right away! Good luck!

Yes move the plants to soil. The seed start moss is holding waaay too much water and the roots will suffocate when you keep them like this. And after you transplanted the plants than give water at least 5 cm away from the seed start moss. You want this thing to dry out completely. The roots will search for the water away from the plant and does develop her roots by doing this.

Are you using peat or is a kind of cocoa fibers that you're using?!? The plantula thrive on a jiffy or you start your grow on this kind of "fiber" soil?!? Depending where you are starting your grow (country)? The seedling is perfectly normal beside that cotiledone leaf that is slightly rolled. In my opinion if you are in a country where now is Spring and you are doing outdoor and if the seed is an automatic I will put it in the soil (final substrate and pot) right now. If you are doing indoor I think that you can perfectly pass right away the seedling from this starting germination tray to the final pot. Normally I only develop the seedlings in smaller germination plates or cube trays when it is summer and I am starting outdoor grows when the weather is very warmth to avoid fast evaporation and the drying of the seedling early roots. So be my guest and pass it right away to the final bed...a good growth for you!
