flushing?

Hey guys I am using bubbleponics for the first time and was wondering holw long do you flush qhen you switch to flowering? Also do I add any veg nutes after switching to flowering and what should my ppm be at

What kind of nutes are you using?

Flushing between veg and flower is not necessary most of the time.
It depends on the grow media.

Some nutes are designed for flower and veg,
and you just change the ratio.

Other nutes are more specific to flower, or veg.
