Hi Stinky

Thanks for the reply. Yes...14hrs darkness.

We have been very careful with the light..the plants are in a closet in a bedroom and the bedroom windows are blacked out. In addition we have a green lightbulb in case we need to use the light.

Temperatures have been pretty constant..about 65 in dark period and 75-80 in the light.

I should add, just in case its the reason for the extended flowering, that we have cut off a small number of buds to sample from about week 7 onwards...but literally only a few very small ones.
