Barney's Purple Punch AUTO DWC

This week started badly due to the root volume in a 5-gallon DWC. I have grown many normal seeds with plants at 80", but I have never experienced a plant whose roots were so refined that they choked off the airflow through the DWC! I took the plant out of the 5-gallon DWC and added more air stones, 8 in total. I put the plant in a 13-gallon bucket and added about 70 drops of PH Up to correct the overnight PH drop of 4.0 due to a lack of oxygen at the root. Everything went back to normal after this procedure. The PH is now 6.4 and I also reduced the nutrients as the plant is drinking water and not as much food.
