Outdoor possible powdery mildew or just dried up water spots?

So these outdoor plants are giving me a riddle I dont like. Whats happening is these white spots are showing up on the leaves, I am not convinced that its powdery mildew. This is the reason why in the full plant pictures you can see random water spots on the plant this is the riddle I have no idea how or why these random water spots are showing up? It looks like the white on the leaves is dried up water from the water spots? Well I would be glad to answer any questions to help figure this out. Thanks much, swizz.

It doesn't really look like PM to me, but an easy way to tell is if you smell it, it should have a musty smell. It will be distinct like clothes you left in the washer for 3 days that you forgot about.

It is indeed PM, cut off the severely infected areas and treat the plants regularly with Oxidate or some comparable product. Oxidate can be used every day and at harvest if necessary as it breaks down into H20 and 02 shortly after application. Good luck

So I have used greencure on these plants yesterday and am going to continue once a week to keep it at bay, Is greencure what youre talking a oxidate or do you know by chance?

Also can you see the water spots in my last two pictures of actually plants? I have no clue how these water spots show up, any ideas?
