Biobizz flush or not?

So ive read contradicting advice about if i need to flush/only feed water last week.

Im soon ready to harvest but i have alot of smaller buds still growing.

So im probably gonna cut the main colas and let the smaller ones fatten to maximise yield.

This brings me to my dilemma, to fatten the smaller buds i should keep feeding as much as possible untill the end right?

But will this mess with taste of my product?

Im using biogrow, bloom and top max with added molasses.

just finished a crap on BIOBIZ never flushed feed it 2 days b4 harvest. smoke was great
