whats wrong with my tomato plant?
I have two heirlooms (Hillbilly & st. pierre) growing in an Earthbox on my roof. For a while, both looked great. In the last week, the Hillbilly's leaves have started to yellow and are sagging a little, the plants seems to have stopped growing, and I've noticed strange wort-like bumps on the stem. On the other hand, the St. Pierre is looking great - it keeps getting bigger and bigger and there are several flowers. I am a first time grower so I have absolutely no idea what this could be. I would have thought a disease would effect both plants given their proximity. It has been windy lately, could this be the problem? Please help save my Hillbilly.
