Hi Guy13,

I haven't done any Mycology for 2 years, but that looks to me like mildew. I believe it was powdery mildew, but could be downy mildew, I'm a bit hazy on the details.

Hopefully this is enough to get you headed in the right direction, the general recommendation is a fungicide and to stop overhead irrigation. The fungal spores can be dispersed through water droplets, fungal lifecycles are a fun read if you have some spare time on google.

Thanks,
- Caleb from Daley's Fruit Tree Nursery
