What is happening to my tomato plant?

Question

I am growing tomatoes for the first time, and so far the plants look healthy and have born some good fruit. Our weather has been extremely hot and then for the past few evenings it has rained a little. Yesterday afternoon, the plants all looked great. Then when I went out today, the stems and leaves of about 1/3 of one of the plants had turned a sickly yellow. Just that quickly! Please help me!

well its not the heat because tomatoes love heat. The yellow is definitely a bad signs, and it might be insects. Here is a good guide that addresses all common problems with tomato plants. It’s made a big difference on how my tomatoes have come out. http://molson5070.tomato1.hop.clickbank.net
