I was thinking leaves are  what pulled water up through the roots as they develop new growth, then they after they mature they are storage for Mobile nutrients, I didn't know the roots push the water up.

Looking back when I Shwazz I do it at the flip and again after 22 days, my records show the water I needed to replace in the RDWC goes up daily through the grow until the last 2 weeks when it slows down. Records from before I started Shwazzing have too many gaps to say either way.
