They had Simon Walton sent off and were well beaten through goals from Patrick Bamford and Dean Bowditch.
Hughes, whose side mustered a single shot of note when Peter Hartley fired against a post late on, said: "First-half performance wasn't bad, we played some nice stuff. But we conceded a real poor first goal and a sending-off at the start of the half left us chasing uphill.
"It was a real bad day for us. We lost three players through injury.
"Are we goal shy? Yes, we need a couple of special people to unlock the door, play that pass, score a goal.
"It's not through a lack of commitment. Sometimes you need a bit more."
