Hey Jessica -- these are my tomatoes, that I started from seed. All I did was order the seeds online from Burpee. I believe they are supersteak and beef steak, and I am giving it a whirl. My family seems to think I have a green thumb, but I am not sure. Some of them look like they have curly top virus, the leaves are purple but not curling. I don't know, but here are the pics and I will see you in August [at the Great Long Island Tomato Challenge] -- with or without a tomato...
 

Kim -- I think you're doing just fine. While there ARE a few plagues that can turn the undersides and/or veins of tomato leaves purple -- like curly leaf virus and psyllid infestation -- they aren't the first things that come to mind because your plants haven't been outdoors yet. Plus, I don't see any of the telltale white specs under the leaves in your photos. They're not impossible, just not my first impression. My best guess is you might be dealing with a potassium deficiency. What growing medium did you use? Have you fertilized? Harden them off for a few days and then get them in the garden ASAP. Be sure to mix in the appropriate amount of high-phosphorus fertilizer for the size of your plot, if you haven't applied it already. Compost, too. And some lime. If they don't bounce back, let me know and we'll take it from there.

Maybe try  talking to them.
