Can’t figure out what’s causing yellowing on upper leaves...

[Dankgg]

Seem kinda weird it’s in middle of leaf and goes across to leaf right next to it... wondering if maybe I had some nutes on my fingers and touched them I’ve been looking and can seem to find answer... out of 6 auto train wreck plants these two leaves are the only issue at the moment

How far is the light from the top? And are these “closest “ to the light?
if only 2 leaves I’d watch and see if others do the same but so far it’s not a deficiency that I can identify.
