quick question about nute/plant..(pic)

hay i been using bloom booster for a little bit now for flowering and the (npk) is 15-30-15. it startin to bud i was wondering if i should keep using this or should i change the nute and if so wat (npk) should it bee using around??
Thank YOu...
(here a pic of it so far)

It's ok to keep using that if you want. You always want a low (N) and higher (P), (K) during your floweing cycle.
