DWC Overwatering?

[NotThaddeus]

So I've got these pretty girls, they are in a recycling drip system and have been showing signs of overwatering, or lack of oxygen I imagine, and I can't figure out why though. I am using GH flora series nutrients and calmag at about 1/4 strength, R/O water, ph between 5.5-6.5, I recently added 2 air stones to the reservoir to help supply oxygen, and the reservoir is 5 gallons, changed every 3 days. What do you guys think?

They are starving

By week 5 I'm running full strength GH flora trio in my dwc when I run it

I don't do top feed because you can cause issues

Word. Ill up the nutes and see how they respond. What kind of issues can happen with top feeding?

Top feeding can drown the roots, especially in rockwool

Why in dwc you keep the water level 2" below the net pot
