Dwc plant wilting

So I came down today to find one of my dwc plants wilting pretty bad. I also thought it was weird because it is in the middle of one of the rows and the rest of th plants are lovin it. Which makes me think that maybe the airstone wasn't doing its job. Since then I've tried to make sure the roots are getting sufficient air. However I feel like its not getting any better. Anyone experience something similar or have any ideas for problems/remedies? Trying to add some photos but can't seem to do it on my phone.

Check the roots for rot. If they are grey/brown and smell funky then you need to add some Hygrozyme.

It's probably fucked. A plant wilts from root rot AFTER it's roots are destroyed, so by the time it shows signs, it's already dead.

That's why I hate root rot.

Did you know that the bubbles from the bubbler are not supplying the water with oxygen directly?

Oxygen dissolves into water from surface agitation... The oxygen dissolves at the water's surface, not under the surface. The more surface area of your body of water coming into contact with air, the greater the DO. So a flat square tote will give you more DO than a vertically oriented bucket with a small surface area simply by virtue of the fact that more water suface is coming into contact with air.

DWC in a five gallon bucket is actually a very poor container shape for DO.

Lordjins right actually the bubbles only help by exposing more of the water to the surface, the surface agitation is what oxygenates it.

From Wikipedia,

"Aeration speeds up this process of oxidizing organic and mineral pollution. In fact, if there is sufficient aeration, the fish will be able to survive, where before they suddenly died. By pumping compressed air out to the bottom of a lake, lagoon or pond with the use of a diffuser, the rising air bubbles and the friction caused in the water will bring bottom water to the surface where it is exposed to the atmosphere. Large volumes of water thus release noxious gases to the atmosphere, water picks up oxygen while circulating at the surface."

I think you might be misinterpreting - it doesn't say that the lake also doesn't absorb oxygen from the bubbles. Keep in mind that, if you were talking about a lake, the amount of air you added would be far less in relation to the surface area, at which point the act of stirring the water would become more important than the air itself.
