Possibly over watering. Yes it's DWC, but overwatering occurs when you don't have enough air in the root zone. Try increasing the air to that pot. If I remember correctly, you need 10 times the air per minute, as the volume of your nutrient solution.

I'm running a 960 pump on 4 , 5 gal buckets but only have 3 gal of nutrient solution. I have 3 other stains on the same air and they are on the same feedings
