I have never done ebb & flow, but I would recommend putting some type of media (like hydroton) under those cubes. Right now with them sitting on that flat plastic I doubt they can fully drain.
All the flood tables I have seen have channels for the water to run off, allowing your growing media to dry out.

Glad to hear they are perking up for you. :hippy:
