Low humidity during the later stages of flowering is said to do this (I've no experience in the matter), but be sure not to drop it too low to early or you might see a negative impact on growth.
I've got a constant battle to keep my RH above 30, so I guess when it comes to flowering I can just switch off my humidifier and see what happens!
