What is wrong with her??

Seedlings feed solely off the nutrients they carry in the seed for about the first couple weeks. It's not until they get to the second or third set of leaves that they begin uptake of external nutrients. Weird things can happen on the initial uptake. Just like when a human baby gets their first taste of solid food. You got yellow coming in with that new leaf... The way it shows up in the symmetry like that has me mildly concerned it could be TMV. But it's also showing on what seems to be the second set of leaves and it could just be that it ran out of its own internal nutrients and you have to wait until it can eat. But always be an optimist when you can, and the optimist's take is it's just a deficient seedling and it will outgrow it in mere days when it's able to actually eat.

I was thinking mutation. I was looking at mutated leafs and they had half yellow leaves like mine. Should I separate it?

Plz look at my newest pics. She looks better. But I have a 2nd struggler. Plz have a look

I had one a couple years ago do the dark tip thing, then I went to jail for my 5th DWI, and left them in the hands of my step daughter and her non smoker husband ,but low and behold it turned out to be some kinda purple something or other, the stalks and stems and even the roots were purple inside and out. I have no idea where or what my seed was or where it came from,so look on the bright side,you may end up with some kinda crazy strain you can name something crazy!
