my small tomato plants look like that when I pot them on (about 4-6 inch). I think its called transplant shock, but they have normally recovered within a day or two, although the stakes look very close to the plants. could this have caused damage to the base of the plants? hopefully, someone more knowledgeable than me can advise.
also, agreeing with others, the ground looks very dry in that bed.
i hope they pick up for you. x
