In brief: No

People have reached their final adult heights and have already stopped growing, by the time they are 21 years old.
Only in the extremely rare cases where a person has continued growing each year, from 18-20, might he grow a bit at 21. That means, if no height growth over the past year, then there will be no more growth.
