Tomato plant leaves

[Bennewby]

Hi guys, The leaves on my tomato plants seem to be curling at the edges, its only on one plant but it is pretty close to others and i'm worried that if its some kind of disease it may pass it on to the others. They are in a big pot, they are flowering well and i have two very small tomatoes on it (still green) Any ideas what this could be? Thanks

Aphids?

Are the leaves discolored as well? or do they have spots? here is a good place to start:
