How is your rockwool? Has it gotten "mushy" or not kept its cube shape?
I started a topfed DWC last month (first hydro attempt, so just sharing my experience!), too. I had rockwool that turned soggy and would fall apart when touching it. I had seedlings in these rockwool cubes stall after sprouting their first set of leaves. It seemed like this caused the rockwool to be waterlogged and the plants looked like they were suffocating.
I've used rockwool in the past and haven't had any issues before with soaking the rockwool and keeping it damp (when I was using it for cloning).
So, my guess is the top feed. I kept a water pump dripping onto my rockwool cubes 24/7, and it seemed like it kept the rockwool too wet. I removed one seedling from the rockwool and transplanted directly into the hydroton. It's alive now, but I'm not sure if I'll keep it.
I started another seed in a rockwool cube, and I've only been handwatering once every day or two. This one's not stalling like my first round!
Hope this helps, just one novice's experience.
