Is it common to have the run off be drastically lower than before you water/feed? I'm a first time grower. Using Fox farm Ocean Forest soil and Fox farm nutrients. Growing Tangerine autoflower. I noticed a few weeks ago some sign of ph fluctuations in the leaves so I started monitoring a bit better. Last week I watered with ph 7.2 and the runoff was 6.1, yesterday I watered 7.4 and runoff was 5.9. What causes this huge difference? I thought maybe it was my ph meter so I splurged and bought a fancier one but still having the same issue. Any help would be so greatly appreciated.
