You need to put that in 12/12 about 7-10days after they pop.I would recommend using 11hrs. on 13 off, being that strain is 90% sativa.According to femaleseeds it will finish about 60cm if you follow that rule.Anything taller than that you'll probably want to cull.They also state that strain is a little unstable.
