Can anyone tell me why the PH on my runoff wont go down. I want to use Atami B Cuz CocoFiber. I started to flush it before planting and the PH runoff was at 7.0. I flushed it once with R/O water ph'ed down to 6.0 and the runoff was 7 still. I flushed it once more with 5.5 and the runoff was still 7. I flushed it for the third time and still the runoff is 7. Can anyone tell me why this is?
