Need diagnosis.
 

Any idea what this is? Spots showed up today (I don't remember seeing them yesterday). Thoughts?

I've not seen anything exactly like that. I've had yellow spots surrounding a dark dot. Stopped it with rubbing alcohol swab and a dry environment. The yellow turned back to green but the dark dot is still there (scar).

Are the spots showing on the underside of the leaf as well?

Yes they do show on the underside.

Swab for red spider mites.

It is not red spider mites damage.

I was afraid of that; I would say that the leafspots are caused by Cercospora sp. It likes to start with older mature leafs and has a habit of starting on the underside of the leaf so by the time you see it on the top side if the leaf it is well established. I would proceed with a fungicide treatment of the plant.
