Off to a nice start! I Use to use tents till I needed more space. Best way to keep them short if you're limited to space would be to either;
-Mainline
-Some Low Stress Training
-Topping/Fim
But @DeathCrusher92 is right about plants doubling in height flipping from veg to flower, sometimes a bit more. My Royal Gorilla Diary shows this as I started off in a tent but soon had to move them, as they grew more than twice the height during the flower stretch. Scrog net can also help. Looking at your pics, you're fine and plants are female.. You'd know if they had sacks 😱 Any queries, feel free to drop me a comment. Good luck!
