Can anyone tell me if this is bad?
I have this tomato plant growing in a pot. Some leaves look like this. I dont know whats going on. This tomato plant, although producing tomatoes, is much smaller and has way less foliage then all the ones I have in the ground. Im not sure if its really clear in the picture, but the leaves are curled and the lines on the side shown in the picture (not sure what they are called) are dark, almost black.
Im concerned something might be going on. Can anyone tell me if I should be concerned?
