Any idea what these spots might be & how I can eradicate them?

could be a fungus, you 'll need spray from the gardening shop.

I'm pretty sure it's a fungus.

Very good photos, faraday.

 

If you have a Thai partner, I would suggest placing them in a sealed plastic bag and sending  some of the leaves  to the botany department of a university in Thailand.     You could, of course,  call them first to ask if they would take a look at what you'd like to send.

 

Yes you could just spray for the unknown but this could  do more damage than benefit.

 

Good luck.

Not.  Appears to be edema.

The leaves shown appear to be chlorotic (yellowed), indicating nutrient deficiencies and/or water uptake issues. (Always show photos of entire tree and site is more informative for assessment, and describe soil and water conditions).

 

I would say work on soil fertility plant nutrition, and water management.  This is the organic subforum, Disregard irresponsible suggestions to guess at fungal disease and rush to buy chemical sprays.
