Hey! My tomato plant has a few tomatoes but the stems and leaves are not going well at all. The past few weeks the leaves have turned yellow and a take them off every time but now it’s gotten to the point where there are so many of the yellow leaves. The stems have also just recently become brown and speckled. Any idea on what it is and what I should do? I thought it was overwatered so I haven’t been watering it unless it light rains and I have been giving it nutrients, but I don’t know what else to do. Please let me know what I should do.
