Hughes replaced Pulis at the end of last season.
"I will send a good luck text to the family because I do want to wish them all the best," he told The Sentinel.
Pulis, a studio guest in London for BT Sport's live broadcast of today's game, added: "I haven't spoken to Mark and I certainly wouldn't give him any advice.
"We are all different as managers and he's got to do it his way, which I'm sure he will."
