His father is only split greywing.
So his mom have to be split for it also
that makes more sense
If he is a greywing, then yes, she'd have to be split for greywing, dilute or clearwing even.
Does he have any black lines on his wings?
In the picture it looks like he doesn't but some opaline spangles have almost no markings on their wings and that doesn't make them greywings. It's also hard to tell dilution in grey budgies, especially from pictures.
