Any plant, including houseplants, will start to develop yellowing leaves
when too much water sits at the roots. It should clear up on its own once
the excessive water goes away. Give it some time and see what happens. If
the yellowing continues, it may be a nitrogen deficiency, but I wouldn't
jump to that conclusion just yet. Too much nitrogen will give you jumbo
sized green plants and no fruit.

a couple of my tomato plants have leaves which are dark green with yellow
around the edges. could this be a nutrient deficiency? possibly a
symptom
of root rot? i have gotten excessive rain fall. i appreciate any input.
