flipping to flower dwc question

hi people so im intending on going to 12/12 today

with coca i know you water with veg nutrients for the 1st week after going in to 12/12

with dwc do i just refill my res fresh with veg nutrients for the 1st week then refill with my bloom and continue as normal??

do i need to run veg nutrients for longer or less time and or do i make the mix a little stronger because of the stretch using allot of nitrogen??

id like to keep it simple as in not having to flush my res unless its a mandatory thing to do before changing nutrients

also do the roots in dwc continue to grow while plant is in flower?? ( i would think yes but that's me taking a guess and im done trying to guessing when it comes to growing )

flip to flowering nutrients after one week of flowering. yes roots do grow during flowering.

Seems that most multi-part nutes reduce the amount of N in the mix and bump P and K. I just follow the feed schedule the nutes came with. Because of this I would drain the system and start with the new mix. Roots definitely continue to grow during flower.
