To me the plants look too small to have any large heads. My plant leaves get kinda huge and make big heads.

Maybe they will make some smaller heads soon.

Too soon yet. September 12 to November 12 is 60 days. There are few broccoli varieties that head in under 60 days and even those slow down considerably with short days. It takes a hard freeze to hurt broccoli so you may still get a crop.

Once you see a head forming, it won't be TOO long. Those plants will produce at some time. Nice looking plants, btw. Like farmerdill said, the brassicas handle frost with no problem.

Agree with the above posters... in short, large plants with no heads showing is a good sign. IME the larger the plant the larger the main head & side shoots.

Our typical winter low temps are in the 25 to 30 deg F range, and usually at these lows for less than one day. Under these conditions I've never noticed any stress on the brassicas. It usually takes lows in the 20 to 24 deg F range to start noticing stressed plants.... So hopefully you have a bit of time remaining before your zone 6A lows will begin to take it's toll.
