do you need a solid state relay for each element you want to run or will 1 relay run 3 elements?

It depends on the current draw of your elements and the rating of your SSR. Keep the load on the SSR at/below 70%. Use the parallel resistance calc for your elements then determine load based on voltage. Use the actual measured ohms of your elements because they can vary even when rated the same.
