hum. bugs! or nute burn
ususally light green with brown spots, over here ive seen it be caused by bugs

honestly id just pluck them off and forget they were ever there, plant looks healthy, dont do anything to it for awhile
on my veggie garden I keep a stock of ironite which helps to keep plants from yellowing due to lack of iron in the ground soil
