In all my pepper growing years I've never seen this. Any ideas what it is? It started as a yellowish spotting/mottling on the leaves on the west end of the garden and is rapidly moving eastward through the rest of the plants. At this point it is affecting about 3/5 of the plot. The leaves eventually turn pale yellow and fall off, some develop "infected" looking lesions like in the picture below. I've had to pull two plants so far.
Yellow mottling on leaves, rear of leaf and close up of lesion. I think after opening the thumbnail you can zoom in further on these.
