I never got to put up last week's pictures, but I knew I needed to get  these up before this week's!  

This picture is showing one of the tomato plant's leaves.  Over the last 3 weeks, we have had cool and very rainy conditions, so it appears that something has started to make the plants deteriorate.  I called the Clemson Extension office, and they told me that it could be something viral, bacterial, fungal, or even a nutrient deficiency (due to all of the fertilizer being washed away from the heavy rains.)  There's just so many possibilities and we couldn't pin it down to one cause.  One of our neighbors had a similar "blight" on their tomato plants, too.  


You can see how some of the zucchini leaves are beginning to be discolored.  The leaves were very dry, thin, and brittle, even with the inches of rain we'd been having.  
Every tomato plant was affected by the speckled leaves that were in the first photo.  

I put fertilizer on each plant and copper-based fungicide (per Clemson Extension's advice), and they appear to have come back.  The new growth is healthy and speckle free.  Look for more pictures later today with much healthier-looking plants.
