It appears to be normal, but could be the start of a bacterial infection.
Those cotelydons (round seedling leaves) are only meant to serve as a nutrition source until the true leaves can take over with photosynthesis. After that, the cotyledons will start to degrade. Sometimes, they will stay on for quite awhile, but it is normal to see them die off.
If this starts spreading to the healthy, true leaves, then you will want to attempt treatment with a fungicide, and let them dry out a bit between watering.
