New garden plants died

Spinach, collard greens peppers and lettuce dying.
I put brand new plants in a raised bed filled with soil from the big box stores. This soil was supposed to contain fertilizer for 3 months. After a couple of weeks the leaves started turning yellow and eventually the plants died.
I put a layer of compost over them, but this did not help.
The herbs in the garden, Rosemary, thyme, oregano and sage are doing fine, however, parsley and cilantro are struggling.

Any ideas would be appreciated
