Hey I can’t see any close up of the leaves, take a look at this resource and then another look at your leaves to see if you can diagnose the problem, it may be just needing a mineral supplement to rebalance despite inherent soil condition http://era.daf.qld.gov.au/id/eprint/1653/6/5probcus.pdfI found this resource a while back on this forum and saved it, think it’s something every Annona grower should keep in their personal library.-joep450

If you are irrigating with municipal water, do consider the high pH that your soil will soon have. Potash will exacerbate this and cause a suite of micronutrient deficiencies. I would start by testing your soil pH before applying potash, and if above 8, I would strongly consider acidifying sources of potassium.
My trees are dropping old leaves like yours.There is nothing wrong with your tree.
