hi guys,
i can't figure out what this is on my tomato leafs. see link above

it has mosaic like yellow spots, my leafs curl, and there appears to be black mold around the edges.

is it mosaic virus or some sort of wilt? it is affecting the lower half of my plant, which has 10 medium tomatoes on it already. i cut away 8 different stalks already, but if i keep cutting them off, then my tomato plant won't have any more leaves!

it appears that the new leaves on top are still healthy. what should i do? keep cutting? or leave them there?

thanks,
jen
