so i decided to get the topsy turvy tomato grower. i admit i have somewhat of a "black thumb" so i thought this would be failproof. i bought a seedling from a local nursery (i believe it is a beefsteak plant or big boy cant remember) the plant is growing great, i have a bundle of 5 flowers that showed up about 2 weeks ago, a couple are starting to die off, i have no other flowers sprouting and no tomato!! it hangs outside and should be getting plenty of pollination as i live in the woods and have an abundance of insects and wildlife. the plant is green and appears healthy however i have noticed a few brownish spots on the main stem of the plant...could this have to do with it? and what should i do to help the plant along. i did use miracle grow soil with fertilizer in it. any help would be great as im trying to turn my black thumb into a greener one.
