I think I have some bad news, I think what you've got is called Leaf septoria; I'm unfortunately familiar with it, in fact I just found it on one of my plants tonight

Not 100% sure so recommend you research and get other opinions but if you come to the conclusion that it is leaf septoria recommend liquid copper fungicide, best of luck

It looks like I have septoria on two plants for sure... the bad one in this post and another with just three leaves with one dot each that I could see easily so.. I’ll pickup some copper based fungicide in the morning and give each plant a detailed leaf inspection and treatment.
Thanks again for pointing me in the right direction.
