I have 4 tomato plants. 2 Roma, 1 baby Roma or also called a grape tomato and 1 yellow pear.. I also have 3 pickling cucumber plants. My yellow pear plant and now one of my cucumbers are acting strange. It started with my yellow pear tomatoes. During the day the leaves will wilt and curl up. Then at night they will recover and they look fine again in the morning. Only to do the same again the next day. The plant is also getting yellow around the edges of the leaves in the lower regions. I have trimmed the yellowing leaves and find no signs of parasites. the plant is slowly producing fruit but is very stunted and is getting worse each day. I grew the same tomatoes last year almost in the same spot last year and that plant got to over 12 feet tall and produced well into late fall until the freeze came. Now I have one of my cucumber plants doing the same thing. Any suggestions?
