Question for all of the Plant Doctors.

Hi All. I recently bought a Dieffenbachia (Dumb Cane) plant that has
developed some problems. It has these yellow spots on it's leaves. Any
ideas what these might be?? See the images linked below.

Look for small yellow or yellowish-orange spots on the diffenbachia's leaves to diagnose bacterial leaf spot. The yellowish spots will have translucent centers and grow to 1/2 inch in size. The infected leaves tend to wilt and die.
Possibly bacterial leaf spot.

Bacterial leaf spot........I guess the only hope is to amputate the infected
leaves.

I'm no expert, just a messenger. Maybe someone else will chime in with help.

I agree, I would cut off the infected leaves
