Forest defended well, but Leeds' inability to score was repetitive of matches over the past month where they have been unable to make a difference in the final third.
The Whites have been without striker Chris Wood so far in 2016, but another absentee has been Alex Mowatt, who has been out with a succession of minor injuries.
Manager Steve Evans told BBC Radio Leeds after the game: "We are disappointed. We've come out of that game with nothing and I think a neutral would think that is pretty harsh on the team in white.
"I think we saw some wonderful passages of play today but the final third was poor. This is a much, much improved team from earlier in the season."
Striker Chris Wood is the focal point of Leeds' attack, but he does not solve the team's lack of creativity simply by being there.
Having him return will be important, but Alex Mowatt could be just as vital when he is available for selection.
Mowatt was due to return for Leeds in their under-21 game at Crewe on Monday, only for the game to be postponed due to weather conditions.
He should be fit enough to play a role in next Monday's first team clash with Middlesbrough, and even if just from the bench, having the 20-year-old available will be a considerable boost.
Mowatt has the ability to change games and be effective in the final third, proving to be a match winner this season and last. Getting him back into the team is going to be important, even if it means Steve Evans having to alter his approach.
