    why is my ph so unstable??

    why is my ph so unstable??

    I had exact same problem. I tried several "cures". Someone said it might help to use reverse osmosis water, so I bought a system and the pH stabilized. Now it goes down VERY slowly and I rarely have to adjust. After some research, I also found that the hydroton I am using may cause pH problems...

    What might cause ppm to rise and pH to drop?

    Makes sense! I guess I am closer to harvest than I thought. The AK47 looks closest to my first-timer eyes. I will get some better trichome pics when light comes back on. Thanks SS

    Three plants in my 2x4 tent. DWC 5 gal buckets. Day 42 of flower. Day 55 of 12/12. Day 101 from seed. The AK47 is the only one with this issue. I am using GH Flora nutes, ppm at res change was 600-650. pH was 5.8. I am using r/o water and adding back cal/mag. Today, 7 days later, ppm 1000...
