Does my plant have a disease or deficiency? See pic
I have planted two tomato plants this year so far in my very first EarthTainer I built. I bought two organic seedlings from Whole Foods market, one is a Pantano Romanesco and the other is a Bush Celebrity. Before I could get my EarthTainer done we had a lot of wind so they blew over a few times in the middle of the night and the labels fell out so I do not know which is which- would need a Tomato Jedi for that.
Recently I noticed one tomato plant has these whiteish spots on its stem- is this normal for either of the two species I mentioned?
