It's LEAF SPOT ... PSEUDOMONAS SYRINGAE
It is a FUNGUS
When you water the plant you should avoid getting the leaves wet
and you should remove the larger leaves.
The rest of the plant can be treated with a copper fungicide.
However, as leaf spot is very contageous it may be better to remove the whole plant .. and DON'T put it (or any leaves you remove) on the compost heap.
