They are all correct you have plants that are already stretched and lanky, you just don't realize they already are and it will only get worse.
You can flower with what you have, but you're going to need to arrange the lights a lot closer and bend the plants over and even still you will get a yield that matches the spindly pictures on that "worst grow" thread or whatever it was called.
The best thing you can do is do whatever you gotta do to get some HPS on them to finish flowering as soon as possible. It will make the difference between getting many ounces or possibly less than one. Do it now and it pays for itself right away.
