I only just found out about wash through, and am surprised it's necessary. So far through about 6 weeks as a hydro noob and wondering if I can avoid all that hastle, changing each tank twice a week is not something I'm enthusiastic about

why would you starve you plants when there growing
even if the plants look ill ,put 1/4 strength but never any

edit to add i grow in small nft for years and never wash through
