tomato plant disease?
It's not entirely clear what is going on with the foliage, but it looks like white spots? To be honest, at this time of the year it is not unusual for tomatoes to look a bit ragged around here. The basic problem is that they are tropical plants in origin and require heat for sustained growth and production. In late May and early June it can be fairly cool, so all sort of odd foliage problems crop up on these plants at that timer. As the weather remains consistently warm, the plants tend to start growing rapidly and these problems are much reduced, or disappear. I would look at the newest growth on the top of the plant-if it looks good then I would be inclined to say the plant is fine. Ensure that it is in full sun, fertilize appropriately and water consustently and the plant should be fine.
