 @47ce6ec1 both early and late blight come from the soil, and usually start at the base of the plant and chase the fruit up to the tips. You can still get tomatoes off of blighted plants. That looks like something else, I don't know. Yellow sometimes means nitrogen deficiency, curling, dark leaf tips is another kind of deficiency, not sure what's up with the black spots. Most of my knowledge is from cannabis, but it gets me through the summer and into a few jars of sauce every year. YMMV
