Could be thrips or the tomato spotted wilt virus.
If you leave it a little longer it may self correct.
But if it's contagious to other tomato plants you be best to water it with a soaker so as not to spread it and avoid touching it and then a healthy plant before washing your hands.
If it were mine I'd leave it for a couple of days and then pull it if it spreads in that time.
