I went to the doctor a few years ago. I told the guy my left elbow hurt every time I pulled on my right ear lobe. The doctor told me not to pull on my right ear lobe.
Long story short, if you are having a problem with DWC, don't use DWC. Try hempy buckets, flood and drain, coco, or regular soil.
I was never a fan of DWC anyway. Overly complicated in my opinion.
As a side mention, I would say stress is a large reason for your herm issues. Your seedlings appear to have nute burn in their early leaves. That could also be from ph issues. Always calibrate those cheaper Ph pens once a week.
