BTW, the leaves on some of my tomato plants are yellowed with black
spots, but only toward the bottom. Leaves from 1/4 up are green and
normal looking. Are these over watered?

This might be caused by over zealous watering. The leaves of tomato plants
should not be allowed to touch the soil. Water should be placed on the
ground gently rather than the water splashing on the leaves. A mulch helps
to alleviate this problem.

See

for specific problems. Read the instructions then click on "leaf". You
will find your problem there.
