SandLake, it's not a nitrogen deficiency. I'm not sure that it's TMV either. The best way to check for TMV is to look at the newer, younger leaves. It usually produces a mottled mixture of light and dark green on the leaf surface. Easy to see if it's present.
The fruit looks healthy too. TMV will affect the fruit.
Disease-resistance only means that a plant will, supposedly, last longer with the disease than a non-resistant plant. It doesn't mean a plant won't get the disease.
One other thing. Those small inner pots are very very small for an indeterminate variety. First thing I'd do would be to pot them up into at least a 25-30cm pot.
