I have two Vortex currently at 8.5 weeks of flower. Mine would be happy to have the whole tent to themselves. SCROG is a good way to go. Also good that you've defoliated the lower branches. Have fun, she's a beautiful perfumed lady!
I usually run 3 in this 3x3 tent and by the end they are usually chocking each other out for light. I'm going for a nice even canopy without the over crowded. It'll probably end up looking like good bondage movie by the end. These vortex have some weak nonsupportive stems but the bud is too good not to keep growing it.
