Looking like you're well on your way to getting yourself a nice little seedling :) The only recommendation I would do here is to add more soil to you're plants base and lower your lights down abit or if thats not an option , raise you're plant up closer to the light . This will prevent it from stretching so much and it will allow it to focus on leaf development as well as node development ! Over all you're doing well keep up the good work .
-Happy Growing! 😎
