My tomatoes seem to be doing ok but I noticed some weird spots on the stem. What could be causing this? Do I have to worry about it?
Thank you

Hi @Derumedice and welcome to the forum. Welcome!

This article should be of help in answering your question: https://www.gardeningknowhow.c...
"If you are seeing white growths or bumps on the tomato plant stems, all you are probably seeing are roots. ... These hairlets can turn into roots if they are buried in the soil. Above ground, they become nodules. These nodules are called root initials, adventitious roots or tomato stem primordial."

Thank you so much!! This article is very helpful. I'm growing my tomatoes in pots and it's hard to decide the amount of watering. I was watering every other day; but, the weather is hot (80s and sunny) and the top soil looked dry. So, I started watering every day. Maybe it's too much? I'm new to gardening so any advice on watering is appreciated.

I generally water mine every other day. Maybe 3/4" or so.
If we get a stretch of near 90 and low 70's at night, maybe I push it to every day but here that is rare.
Conversely if I get upper 60' to low 70's for three or four days, I might water every 3rd day.
I use the schedule and never pay attention to how dry the soil surface is. But please keep in mind, my 👀 have 55 years of experience growing tomatoes!!!

Thank you! I will go back to my every other day schedule as you said! Hope the spots will go away as the article from Moonshine suggested root and stem stress due to overwatering!!

I grow most of my tomatoes in 5 gallon buckets. On hot and sunny days, the surface will dry out quickly. My rule-of-thumb is to stick my finger into the soil about an inch or so. If it is fairly moist, I don't water. If it's not fairly moist, I do water.
