health Spots on leaves and leaves falling off

[svcook]

Any ideas what this is? Could it be bugs? I though maybe a fungus so I did spray with a fungicide.

I haven't spotted any bugs other than the ones pictured below.

I have a lot of these, but I think they are good?

I've never seen any of mine do that before.

I have succumbed to bad weather, ferts/sun burn and beetles/aphids a time or two.
Yours looks different.

How many do you have that looks like that?

looks like it could be fertilzer burn. pinch off the really bad leaves. if it is black spot or some other fungus, you don't want it to spread. make up a light mix of baking soda and water and give it a light mist. baking soda fights bacterial fungus.

good luck.
