First of all let me say "VERY NICE PLANTS". That density of growth means they are probably females so I wouldn't worry at all.
They are about to explode! myn finished at around 30 inches height and I flowered at half of your height I think 7 nodes.
I would suggest LST now because with CFL light penetration sucks and your going to want to get as many tops even with each other as possible to utilize the CFL's as effeciently as possible. I can see you are obviously good at TLC which may allow you to effectively use side lighting it is just easier to have a LSTed plant.
You doing anything for stench? I would suggest building a cab with another rubbermaid to seal off the grow. stacked upside down on the other one. like red's here
International Cannagraphic Magazine Forums - Red_Greenery's Handyman's DIY Grow Tub You will need to ditch the mylar if you do this as it holds in all the heat (reason its a safety blanket). You will want to paint the insides flat white.
Build a small scrubber like the one seen here to deal with smell and ventilation
International Cannagraphic Magazine Forums - micro carbon scrubber very easy very cheap.
I would suggest cutting back on the nutes, Your leaf tips are curled down this is either a sign of over watering of over nuting. Cut back half strength untill they straighten out and then hit them again. You will see more growth if they are not over nuted.
Regardless awesome looking plants and very well documented journal!
Im going to die if i don't see something soon. 
. Very stressful. I need to quit getting my hopes up though.
