Gray Leaf Spot?
I think some of my plants have gray leaf spot, at least the symptoms best match that of gray leaf spot. There are small pin-point size brownish-gray spots on the lower leaves and it is slowly works its way up the plant. The spots are more visible on the undersides of the leaves but can be seen on the top sides of more severely affected leaves. What really concerned me was the presence of irregular shaped brown lesions on the side stems (not the main stem of the plant). I'm fairly certain it is not early blight as the spots are very small and there are no concentric circles. I've sprayed 2x with daconil about 7 days apart and I'm crossing my fingers that keeps the problem at bay. Do these symptoms sound like gray leaf spot or could this be in fact early blight or something else altogehter? The pictures on the Tomato Problem Solver are hard to differentiate at times. Thanks all.
