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
cheers all
