I like to get that flowering mechanism triggered as quick as possible so I give them flower ferts as soon as they need watering after being put into the flowering room. I also like to wait for alternating branching to be well underway so preflowers can usually be spotted and the males set aside leaving more room in the flower room which is usually around week 8 or so of veg.
