It doesn’t look that bad. If it’s continuing to grow fan leaves with only 3 blades like that, there’s still an issue going on though. They’ll do that when there’s some sort of stress or problem happening but then go back to normal leaves with 5-7+ blades once the problem is resolved. If it’s not getting worse then I’d just ride it out.
I just tried DWC for the first time but it didn’t go well. Root rot very early on from high water temp and I probably stunted it with frozen bottles of water trying to correct the temps. The first time I’ve had to kill one of my plants and I hated so much to do it. I always finish out a plant no matter what happens to it but I’ve found DWC is just a little too much for me at the moment.
