The cold and lack of light will slow the flower development a lot.
You have autos, so try to get them as much light and warmth you can inside.
Low light and no light are quite different.
If your plants sit in complete darkness they will die quite quickly, but in the livingroom, I'm sure there is some light from outside, even if it's overcast.
I can see your flower on the plants is quite slim and small from the cold already.
In future line your auto up with your good weather so it's done before the cold and short days come.
It makes life much easier and you get more reward for less effort. ;)
