No, parrotlets do not need grit or gravel. I would also stay away from any colored pellets, natural pellets are fine but not the colored ones for p'lets.
We feed ours a mixture of Higgins small safflower gold cockatiel and conure with black oil sunflowers added along with natural pellets and plenty of fresh fruits and veggies
