the cutting edge nutes has no flower boosters what to do?

Hey guys and gals im just now into flower and my first time using cutting edge so far im loving the nutes but am a lil sad they dont have any flower boosters so I was looking to see if anyone thats using this nute what boosters they are using from other company's or if its not needed I used house and garden before and was thinking of getting there stuff but not sure if it would work with cutting edge or if there is something just as good but cheaper cuz the price of house and garden is why I switched to the cutting edge in the first place. Any help is much appreciated.

you can just buy pk13/14 or something.

Dont buy advance nutrients bloom boosters. same product and double the cost.
Read what the nutrients are derived from and you will see that they are all made from some kind of monopotassium phosphate or potassium sulfate, etc.

Bloom boosters are just not required when running CES, as the 3 part lineup plus the 3 additives provide the plants what they need. If you must add a booster, liquid (Budswel) guano works great with CES.
