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.

Could be a nutrient deficiency caused by the excessive rainfall leaching nutrients
beyond the root zone. With root rot I'd expect wilting.
