the t5's will bloom you good...the 2700k is better for flowering...the only reason for adding the blue scale is a little uvb added in the mix! Won't take any longer and yield change won't be huge! Enjoy the grow my brother every grow get's better.. As we smarten up!! Try to improve and keep mental record of problem's and don't repeat and wow what a difference..plant's only photosynthisize from the top of the leaves! Light below that point is wasted keep it up let the plant grow to it. When you switch to 12/12 to bloom make sure it receives no light at all durring dark 12!!!! This is verry important as it will stop flowering and may turn into a hermphrodite not wanted!! Wishing the best my brother!! Jack
