Peach trees disease?

Peach    Costa rica

I have several trees infected with the same disease. The oldest leaves are the most damaged. The leaves have small yellow spots and purple stains.

Thank you for your response. I have uploaded two more photos showing both surfaces.

Hi Fabiola, is it possible to upload more images? Also, it will be helpful if you take pictures of both surfaces of leaves. Thanks

Fabiola, after further searching I found a Plant Diagnostic Clinic page that makes me think your peach tree may be suffering from oedema (a physiological disorder) rather than rust. How often do you water your tree?

Agree with Kelsee, it could be rust disease. There is clear evidence of rust pustules on lower surface of leaf. For more information

I'm thinking that could be the beginning stage of shothole fungus:
