Hello all. Here are a few pics of my issue with my tomatoe plants. There are actually 3 plants, 1 roma and 2 cherry. My wife & are growing them in a topsy-turvy upside down planter, and even though it is growing nicely (installed when they were maybe 5-7in tall) I have noticed some issues on the leaves and stem. I am completel;y new to this so any help would greatly be appreciated. Thanks in advance.
