How to introduce bloom when flowering

Hi people,here goes. Just put my plants into flowering today they are looking good for my first time,already posted pics on other threads. I know during flowering boost nutes are needed for better,bigger buds.This is what i am unsure on remember am still new to growing.My ten plants have been on canna coco A&B during their vegative stage throughout! Do i cut out the A&B nutes all toghether and feed just boost nutes? or add the boost nutes along with the A&B?

This may sound retarded but i am unsure,this is a simple question can any1 give me a simple reply?

Yes you put the boost in on top of your usual nutrients.Unless (I'm overly stoned; it doesn't even register on my EC pen.)
Hope this was simple enough..

Thankyou very much,goes to prove my mum was right,if you dnt know just ask lol,cheers mate.
