canna pk 13/14

hi folks need some advice i bought some pk 13/14 to use during flower now the guy at the shop said to use aroundabout week 6-7 and only for one week so i can bulk up the buds so what do you think.also i use canna flores and 120ml A to 60 litres of water and 120ml of B to the 60 as well.so it says on the back of the bottle to use 150ml to 100 litres of water but the guy said to use 120ml and just add it to the A and B and maybe feed them twice out of the 4 times i would normally be feeding them aroundabout that time?cheers folks i just dont want to use this and it goes tits up.

anybody???
