I went outside and found the same problem with one of my bell peppers this morning... all but two of the lower leaves are limp, and the top drooped over, but not dry. I cautiously checked a couple of the roots for nematodes and moisture level of the soil. Neither are the culprit. I checked for insects and possible borers, but again nothing.
After checking my garden this afternoon, my tomato plant is beginning to have the same problem on one lower stem.

I did lay out some bone meal and general plant fertilizer last week, but not much, and so far none of my other peppers have been affected, although they are much smaller right now.

Any ideas?

So I went outside yesterday and it was over. I pinched off the upper half of the pepper plant and found a borer had indeed made it's way in there some how. There was no way for any further grow on the plant so I finished pulling it up.
I pinched off the affected branch of my tomato plant and found the same thing. Strange thing is, I inspected both plants and still could not find where they made their entrance.

Did you figure out if this was your problem or was it something else?

Now to tackle my beetle issues on my broccoli raab...

didn't bother inspecting but rather just tossed the bad plants. What kind of borer was it?
