When i do Drain to Waste I keep it at 5.7.Wow, I run my pro-mix at around 6.3..............
Im sure pro mix can take a large range in PH but since its a soilless medium and doing DTW i consider it passive hydro and run my PH in the hydro range.
I'm not an expert but when i run other plants in promix at a higher PH they don't seem to eat up the nutes as much and don't pack on the weight
I was told about this from a Master Grower and he didn't explain all the reasons behind everything but its working for me.
Watch my next grow...im going to try to run the DTW to an extreme and pull a massive yield. Fingers crossed.
