Dark edges can be from too much or too little water. Is your pot well drained and all water removed from tray after it drains? They don't like to sit in water. Not enough humidity can also cause brown edges. These plants need high humidity.

Because your plant's spots have the yellow halos, I think it may be a bacterial infection. Remove all the leaves with spots and destroy them. (But not all the leaves.) Then look at the care articles below and see if any of the cultural tips will prevent the spots from returning.
