She looks ok...

The yellow leaves are a concern.. It is probably 1 of 2 problems...

1. You are over watering and you have suffocated the roots
2. You are using a soil that has been pre mixed with fertilizer/nutrients and it is to powerful for your seedling...

Around day 9 and 10 after the plant has established some roots, you should begin to see vigorous growth...

Thanks for the pic, keep them coming.
