Welcome to Lumberjocks, Nuvigil. Unfortunately, you are correct. A jointer cannot be used as a thickness planer. The jointer works well to flatten one face and square an edge to it, but once you flip the board to it’s other face, there no reference to the already jointed face. You will most likely end up with a wedge. You either need a planer or some hand planning skills.
