One thing that jumps out is that the plants appear to be potted too deeply. You want the bases of the plants right at the medium surface, not below it.
At this point, you may safely grasp the plant, and while jostling the pot a bit, pull up gently on the plants to the proper position.
You may find that the plants will be a bit wobbly (precisely why most folks plant too deeply), so stake the plants until they "lock in" with their root system.
