Note to Self. Next time trying to Perform DWC System with the skill of an Organic Soil Gardener. Take into consideration Water Level, Water Temperature, Nutrient Solution ,PPM, Ph, how much light is the solution getting, air flow, water flow, wait another week or two before adding Open Sesame, start out at 300 ish ppm and work up a extra Veggie Cycle is better than no Veggie Cycle.ppm was 1750 is So, I flushed the Rez’ washed out buckets with Dawn. Refilled the Rez with Distilled Water &with 1 Tsp 3% H2O2, Per Gallon. They will soak there for 12-16 hours before adding 800 ppm of Nutes. The yellowing started at the bottom section of leaves and crawled up. Root Rot?
