Ok...I got the part about the soil.....but what about the water or nute solution you are pouring? Should it or should it not be between 6.2-6.8 or does it not matter as long as the runoff is normal?

Sorry for threadjack sy, just want to clarify something I'm not sure of and it still fits in with your question (I hope.....)
