I have been a reader poster for a while and have had few issues with my tomatoes until now- I like the advice DigDirt gives so I am asking for your help now. I have about 100 plants, heirloom and hybrids. They are dying. THe leaves from the bottom up are turning yellow and dying. I dont have any pics of this BUT it looks exactly like the plants in the posting " Yellow Leaves- Are my plants toast?" I notice there are several of us having this problem and so far no help. Please tell me what it is and how to make it go away.
