Angel Martinez scored the winner in Blackpool's 1-0 triumph over Leeds but Warnock felt that his team should have been given a spot kick in the first half after Ross McCormack went down under Stephen Crainey's challenge.
"I thought it was a penalty," said Warnock.
"The ref said 'there was something not quite right' - I don't know what that means.
"It's a booking if he thinks he dives or it's a corner kick if their defender's got a touch, but on the video the defender's got nowhere near the ball - he's just taken Ross down."
Leeds now sit 12th in the Championship with two games left to play.
