I hope this is true. I have never had a seedling come up yellow. Always green. Good luck and I hope it works outJust broke soil, which it a fight for a seedling, and under the soil is dark, so no light. It should straighten and green up over the next few days.
you did this before the picture was taken? that is a a lot of stress.. that very well could be your problem sometimes they are slow to come up but what every you did, didn't help.. matter of fact I'm not sure if I see your complete picture you're coloringOk, i tried a full day in unferted soil, it didnt do dick, it dried out and clumped hard, even with perilite added. I change the taproot over to a pellet and boom, it pops out of the stem and comes out over night.
