MSU 19-4-23 and Bud Candy

Hi folks, simple question here, I’m using the MSU 19-4-23 on my girls and they love it. I’m looking forward to flowing time and have been looking at what nutrients to go with. At this time I leaning towards something like Bud Candy.
My main question is when I do start with the Bud Candy do I completely stop using the MSU 19-4-23?
