I am having a very similar problem. I have the 9 pod garden. The 3 tomatoes are one side and are tall-ish (there is some fruit) and leaning to one side. I also have Yellow Bell Peppers that are doing OK and on the other end. I have Yellow Hot Peppers in the middle, they are growing the best.
I have my garden in an area where there is no sunlight, could that be a problem.
Also I read elsewhere on this blog that I should be using distilled water, could that be a problem.
A final question, is there a problem adding Miracle Grow ??
Many Thanks in Advance!!!
