Can anyone tell me if these young tomato plants are diseased. They’re planted in a raised bed with Miracle Gro Nature’s Care Raised Bed Soil. If they are diseased, will I need to replace all the soil?

They are not diseased, but this is a very common problem with Miraclegro soils in general. They are far too concentrated with nitrogen, and tend to burn young plants.
Dolomitic lime will help here to some extent, but it will take awhile for the nutrient content to be washed out some.
Next season, I would amend with some compost, and wettable sulfur to kill off anything in the soil, and give back nutrients that will be a little more gentle on the plants.
