Well, I Measured my promix runoff and it was 2000 PPM.

Plants were very unhappy this time around, I flushed them real good, but it compacted the containers so much, that I think this crop is all but ruined. The Promix compacted about 2+ inches when I flushes to rid the high PPM!!

Thanks for the heads up Tranoble, I guess I have always cut the promix with organic soils in the past, never done straight promix HP


I am using Promix HP (white bag)
