Question About Top-Fed DWC

My DWC system has a top-fed water supply from a water pump running into my 4 active rr's 24/7. They are extremely saturated with water. Plants are 2 weeks old and are slow growing, changing color to bright yellow, and drooping. Is the water pump killing the girls?

What is 'extremely saturated with water'? It's a Deep Water Culture grow.

Additional information and pictures would be helpful.

The only issue I would have with a top feed system would be if you use rockwool as the media. If I run my system to full and the cubes sit in solution they can cause damping off(stem issues). If you don't use rockwool or something that retains water, top feeding shouldn't create your issues.
