Is this Tobacco Mosaic?

Hi-
I am wondering if anyone might be able to help identify what is going on with our tomato plants in the pictures I have attached. I am worried they might be affected by tobacco mosaic considering that one of the people who helped us transplant them is a smoker. I would love to hear some thoughts.
thank you in advance!!

None of them look like virus damage. The first picture looks like leaf drop from low fertilizer and low light condition in shipping. The second and third picture look like frost damage.

 

Thanks for the reply, it's good to know it doesn't look like a virus. We started them all from seed, after the last frost here in the house (and they were in the greenhouse until a couple weeks ago on top of that). We've never used fertilizer either.
Thanks again.
