Problem. Yellow, orange spots that grew to cover one full fan leaf

Here is a photo of it. Not sure if its bugs or not. I couldnt see anything on the underside of the leaf. I hadnt noticed it on this OG Kush girl because the leaf was on the backside underneath. Started looking when I saw the spots on upper leaves.

Any help would be appreciated. And if I have posted in the wrong area, please move it to the right one.
