What is plaguing my tomato leaves?

[Poodlelady]

Hey! I have very small black "spots" on my tomato leaves. We had LOTS of rain a few days ago. Other plants are showing signs of overwatering. But, one of my tomatoes has develop "spots." It is on new growth but started a few days ago on old growth. Overnight this happened to the new growth? What the heck? Advised, insight?

Hi!

Have you had a few nights of cold temps lately? It looks most like cool weather veining to me, but it could be a few other things.

My plants do this sometimes from transplanting.

Phosphorus deficiency can cause purple veining similar-ish to that.

I don't think it's disease related. I think it'll likely grown out of it with a small amount of heat, some plant food, and good ole time!

Welcome to the forum! Love the nails!

Lindsay,
We have had about 3 cool nights... right after the rain. I cut off the effected area... hopefully you're right! Thanks!
