Black Spots On Soursop Leaves

Question

Hi fellow gardeners, I’m in Brisbane Australia and am growing a soursop for about a year now in a pot. It’s growing slow but steady but since a few months now it’s developing black spots all over its leaves. (Please see photo’s) Does anyone know what this is and how to treat it? Thank you, Andy
