Yellowing of seedling

Hi there To me they look fine at the moment just keep an eye on them as they get bigger, try not to over water as there so small in such pig pots 👍 Best of luck

New, young growth is often a bit wonky - either in terms of shape or color - and is really nothing to worry about. And if she's different from the others, just remember identical twins aren't really identical! This may be HER pattern - to send up new growth that is lime green but that will turn a better green as it gets older. For now, I wouldn't worry at all. Good luck!

Btw they need humidity domes asap, all pot not overwatered, thats good, but by look they are too dry, not good for seedling stage.

Is it yellowing or lime green, fresh grow, rapid grow always comes up like this Only overfed plants develop slowly and theirs leaf colour is full of chlorophyll. If yellow worry, either heat/light intensity damage, raise light. Or nutrition damage , flush or restart even .... Or ph , could be needed flush , possible restart. To me its all good, but i see photos, not live ... Happy Growing !!!
