I am new to growing tomatoes a complete newbie. I'm using one Topsy turvy upside down tomato planter.
I've gotten a few tomatoes from it about eight, but when I went to check on the plant I notice the stem connected to the yellow flowers were a purplish color, the leaves aren't purple. The big main stem isn't purple just near the flowers. It rained last night also.
It seems to have happened overnight because I think I would have noticed it yesterday, maybe I just wasn't paying close enough attention.
Any help would be appreciated.
