Those things are incredible. I started growing feminized Jock Horror seeds from Nirvana around the same date you started. Mine are only 3 feet tall! Ha. Your trees have really filled out nicely. I'm hoping to get to about 6-7ft by the time I harvest. I would be plenty happy with that for a first grow.
I considered Kaya Gold as I remember reading it was hearty and did well in hot weather. It sure looks hearty alright! Mine only get about 6 hours of sun per day as they would cook in our 110+ F weather. My plants' nodes are extremely close oddly enough, but they sure aren't growing like yours.
Ha, I just took a look at my most recent pic and it almost made me laugh how much smaller they are. Oh well, when I rub the stem the smell is INCREDIBLE. Can't wait to smell/taste the buds. How much longer do you have till harvest? I'm looking at another 3-4 months.
