[tomato] Leaves turning yellow from the ground up

OK, this has happened for the second year in a row

I have huge, healthy tomato plants. I'm growing them
inside cylinders of chicken wire, and they seem to
love that. We have lots and lots of blossoms and quite
a few 1" green tomatoes growing.

However, the leaves are starting to turn yellow,
starting with yellow patches on green leaves, from the
ground up. I've tried dusting them with a copper-based
dust, but I'm not sure I see any improvement.

They are weird-looking plants -- they look totally
healthy on the top, but sickly toward the ground.

I've been trying to research this problem. At first, I
thought it was manganese deficiency, but in that case,
the plants wouldn't be so huge, I think. I've read a
little about fusarium, but I'm not sure that's it
either. Can anyone help me understand this?
