That's what I thought because of plant size and your guy's veg season has been over the last few months. I've been living vicariously through the Austrailia threads and from what I understand everyone's stuff is starting to flower or about to. Keep a close eye on em and move them somewhere so they'll get total darkness if you can. If there are outside lights keeping them vegging then try your best to kill the lights. A back porch light left on or something will keep a plant going if it's close enough. There was a guy who had that problem in a thread here in fall and it was due to his wife taking the dogs out before dark and letting them play in the yard. She'd turn the lights on and it kept his plants vegging very late.
I'd have that problem myself cause I have an apartment complex the next street over and the parking lot lights keep my yard lit up at night. It's so strong seedlings react to it and will turn towards them at night.
Yeah some people are night owls (myself included) So I could see that happening in my case.
I suggest OP over that window up with something (lightproof it)if he's going to keep them there. Even a few thick layers of dark cloth will do the trick. Or a big cut out section of cardboard. You should also jump in the Australia threads and ask those guys there about flowering times.
