Help! I have never been able to grow tomatoes successfully. I get a few blemish-free, but most of them are riddled with black spots. The plants are beautiful for the first 6 weeks of being planted in the garden but then the plant starts to turn yellow, then I get black spots on the leaves and the stems and finally on the tomato itself. The plants are not stunted. I did a soil test and it turns out it was nutrient deficient. I started to fertilize the garden but the problem did not go away. My soil is made up of native soil, cow manure, vermiculite, peat moss, bone meal and limestone dust. Please see attached photo.

Your tomato looks like it has Bacterial spot. Sometimes the plants and even the seeds are already infected and spreads once it is in the garden, and it can be spread on your garden tools as well. Warm, humid weather spreads it quicker. The nutrient deficiency you mentioned can also stress the plant and make it more vulnerable to disease.

Do you plant many tomatoes? Are they planted in the same soil every year as well?
