Even cow manure and horse mature can burn plants if it's not dried enough or so I was told.

Carmen, I am very sorry about your garden. If after proper sanitation and an organic schedule of organic fungicides does not help, you can try to contact the Extension Service to see if they know the cause and they can help, hope that your garden gets better...

More of a question than answer but...

Could it be that the couple mornings that it dropped into the 40Fs combined with the low humidity high winds stressed them just a little?

I think it could be the wind too. My tomatoes developed purple/blackish tints to the leaves from the wind.

chuggerguy and amberose I think you may be right. I also was reading and article about the solar flair being very high last week.

Who knows I trying a couple of sugestions from pro's, see what happens.
Thakn you all for your help

It's the dryness and wind. Having same issue.

def dryness and wind, coupled with the heat. The leaves are wilting much quicker as the recent wings have been sucking up the moisture.

Is it happening mostly on the bottom sets of leaves?
