do i continue with flowering nutes?

Hey guys
ive been using big bud, canna a+b, b52 and overdrive in pure coco.

Just at 8weeks, and finished 2weeks of the overdrive. 2 plants are getting flushed coz their ready to harvest.
2 plants however need at least another 2weeks.

Do i continue to use the bigbud or just stick with the a+b till they finish

cheers in advance
