Yellow Leaves

One of my 3 plants leaves are yellowing. Does anyone know what this could be from? The plant is about 2 weeks old, ill attach a pic right now from 2 days ago. I'll add a more recent one soon.

This is common for the first leaves to yellow and fall off. No worries

Thanks, thats good to know. the only problem is the top leaves have also started yellowing since i took that picture as you can see in these pictures... I have also re potted these plants since the other photo thats one of the reasons it looks so much larger but the growth has actually stunted since the leaves yellowed.


Am i worrying myself over nothing, or could there be something wrong?
