BongRipstarted grow question 4 years ago 2181ppm! My run off ppm got very high at the water at the end of this week. I boosted them with 7ml/gal of earthjuice big blooming guano + 2.5ml/gal earthjuice meta-k. The initial water ppm was 176ppm. Should I flush it off immediately with plain ph water? Please help guys!
