Reds boss Billy Davies expressed over the weekend that he was hoping to bolster his ranks before Monday's 11pm deadline, allowing Forest to build on a productive opening to the season.
They were in the market for new recruits as the clock ticked down, but saw inflated asking prices leave them empty-handed.
Chairman and owner Fawz Al Hasawi feels the club can still be pleased with the business they have been able to complete - with several fresh faces drafted in - and says attention will now turn to the loan market and the identification of targets for the January window.
In a statement released on Forest's official website, he said: "I would like to take this opportunity to inform our supporters that we today (Monday) attempted to sign four players in a bid to further bolster our squad.
"Regrettably, the value of each player rose over the course of the day to a point where we no longer considered any of our targets as suitable signings at this time.
"This should not detract from the work we carried out earlier in the window. A lot of money has been invested and I am delighted with the nine players we have brought to the club this summer. The early additions have allowed us to make an excellent start to what I'm sure will be a very memorable campaign.
"We will now turn our attention to the loan market before having another major push in the January transfer window."
