I'm sure others will give some more suggestions however, I liked to do a flush before switching over to flower nutes doind DWC. This also allowed me to assess the roots to make sure there is no "sludge" or algae on them which could prevent nute intake. Make sure you pay attention to the water level in DWC as this is the plants main intake of nutes and O2 via the bubbles and will surly hurt them if you allow your water level to get too low.


Hope that helps
