Stress - Reproduction?

Hi all people on RIU.
I've got a problem with my Blue Cheese from big buddha. Its growing indoor in a closet
It started flowering very well, and got some fine small buds. But then it suddenly started to grow taller, but without any buds on the part that grow taller. but other buds still remain "unstressed" if you can say so.
I have used Vitalink: Bloom/Flower, BioPlus, Fulvic, Buddy, PlantStart and Flush... FIY, the plant havent been given any Flush yet.
I really dont know what that could have caused this stress..

looks like its going back into veg?

yeah exactly. The plant was born 10 march 2011. and got into bloom 25 may 2011. If that could help.
