don't trip it looks fine right now. By the looks of the soil it may be a bit underwatered, but don't go overboard with it. Possibly your soil is too coarse for the plant but I don't think that would really hinder it in any way. What is your lighting and water schedule. How much? Do you have any fertilizers going cause you shouldn't.

well at 3 weeks i usaully start feeding nutrients.
they do look under nourished
and the yellowing could be a magnesium deficiency, curable with epsom salts which can be aquired at ya local chemist
mix about half a teaspoon of epsom to 1 litre of water, making sure that it is completly dissolved ,and water like normal with the solution
i also spray down the leafs when the lights go off and this seems to help
hope this helps m8
cheers all

well after a closer inspection they dont look that yellow on the top
and the 2 leafs that are going yellow on the bottom are perfectly ok, as
these 2 leafs hold all the nutrients for the seedling, once the seedling has used up all these nutrients the leafs will look crispy and fall off , then you can introduce nutrients to the plant this usally takes 3 weeks
