Hi, ive been looking through your Diary and the Girls started to flower in week 11, that means you are in 3.rd week of flower. I think your Girls will need 7-8 more weeks in flower.. The only thing your GIrl need now is TIME. Nutrients by itself wont help alone. Its always the big Match of LIGHT, POTSIZE ( ROOTS) And TIME. Your LIghts are good, Potsize is fine. Dont overdo it with The Nutrients, save your booster , give it in 4 weeks . Happy growing
