Please help my figure out what wrong with my plant. The first pics are from a few weeks ago and the last one from today. The plant took off at first and I had a tomato right away.....now it seems to have slowed a lot with growth & has only set one additional tomato. I have added episom salt but it has progressed to the new leaves as well. Thanks for any help you can give. The plant is in a 5 gal bucket if that makes any difference.
