Tomato problem (I think possibly virus or bacteria)
One month ago, top upper stem
One month ago in some tomatoes (less than 1%), the upper and young stems and leaves started to have spots and turning into a purple/grayish color. You can see this in the first two pictures 1 and 2. Right now--after 1 month--all of these young stems and leaves are completely dried and dead. The tomato fruits these tomatos wield are looking like in the photos 3 and 4. I think it's a bacterial or viral problem but I am not sure. Can you help me identify it?
