That's your problem. Cubes, ESPECIALLY Large cubes like yours are not meant to be in a DWC, you will drown your plants, or at the very least they cannot thrive. When there is that much rockwool it will never get a chance to dry so that your plant gets oxygen.

You will either have to either reduce or eliminate the rockwool from the plant, or set your plants on a tray the way they are, and feed them water/nutes by hand. I would not water them more than once a day or even every other day.
