looks like it needs water to me
Those are just the Cotyldon leaves, also known as the "seed leaf".
They usually die off a week or two after the seed germinates. How old are the sprouts? Howl long ago did they emerge from the soil?
Id say water the lil girl (hopefully) and watch your PH !! What type of soil are you using ?
Looks very small for 10 days old...how often do you water?
Also anymore advice ??
