I am having the same problem, any help is greatly appreciated. Also if someone could remind me how to post pictures I can put pictures up as well

Here are the pictures of my leaves, one is in the ground and the other is in a container. Too much water maybe?

I have this that same spotting on my tomato plants, I am new to this, its my first time growing tomatoes. Do you think it could be from too much water, I was afraid it was a disease or some type of bacteria growth. Can anyone help?

My spots are more orange than yellow, almost a rusty color, but I know that color is subjective. I have read the feedback and still haven't found a solution, just that many other folks had this problem. I'm in zone 7 and planted some seedlings as I'd arrived too late to plant from seed. They were doing great but the lower leaves of 2 out of 4 plants have these dry looking orange spots. Any ideas of what to actually do about it, what it might be? Thanks!!
