yellow leaves and cotyledons

I think there is a problem in the ground. germination on a towel, then she went into moist soil. practically 10 days without watering. I have the impression that she is fighting, waiting and watching

I advise you not to water too much and do not touch the stem during watering, otherwise excessive moisture in small seedlings can cause damping fungal disease.Good luck my friend

I've just seen that you had posed this question before - but with different pictures... had not realized you'd had a humidity dome on her! For 10 days?!!!?? You suffocated her! Plants need fresh air - they need oxygen to their roots but also oxygen to their leaves! My answer below still stands in that you need to pop some new seed - but this time, once that little one has broken the soil, there is no need to keep a dome on top of her... and do not drown her by watering too much. You need to provide a good humidity so you might want to put a humidifier in the tent with her but the dome is just a no-go... the humidity in the tent should be about 60% for seedlings. Good luck...

It's most likely challenged with either water or it's hard to come out of the shell giving a weird visual but another thing I've noticed is that your seedling's leaves are raised up this means it can fight

To be honest, this just looks like a mutant... and she should be MUCH bigger at this point. Sorry to say but I'd give up on her and pop another seed! And if you DO pop another seed, start a diary so we can take a look at everything you do to her/ give to her should another issue come up... Good luck..
