My young tomato plants were doing fine unti I transplanted them to a new pot. now they're dying. what do I do?

they are getting close to eight hours os sun and plenty of water. Do I need miracle grow?

they go into shock when you transplant especially if you place right in the direct sun most plants need to be in a little shade after repotting you did not say what is happening to the plant so my guess is shock and yes miracle grow for veggies does great do not over fertilize good luck
