New gardener needs help with spotty leaves please!

[sweetdz]

I have only been growing tomatoes for two years so any help would be greatly appreciated. I am growing about 10 tomato varieties (all OP except 1) this year. They got a little cold damage the day after they were transplanted but seemed to be settling in well. I went to check on them and pull suckers today and found that one of the plants has spotty leaves. It is the one F1 variety I planted this year -- Sun Gold.
Nobody else is showing any spots except this one plant.

I battled bacterial spot last year so I am pretty familiar with what that looks like but this looked a little different to me. Any feedback as to what this might be and what to do about it would be great!

Thanks,
Kelly
