You should consider starting the seed in soil that is made for it. If you dont want to repot, start it in a jiffy starter in the larger pot of regular soilI planted a seed and it grew but it’s just the stalk and no leaves. Does this happen sometimes. I’d understand some stall and some tiny leaves but this is just the stalk unfortunately
Your pictures are not clear enough to zoom in and see details. You sure you don't have the seed membrane still on there holding the Cotyledons closed? That is a very common issue. Can you post a pic close up to the top of the seedling?I planted a seed and it grew but it’s just the stalk and no leaves. Does this happen sometimes.
