So I have gotten to the point where I need to start testing my run off so I did. I came up with the same pH that I am feeding in Fox Farm Ocean Forest with RO water having 1/4 strength GH nutrients. I read 6.5pH from my runoff, but my ppm was exceptionally high, up towards 2400ppm while only feeding less than 250ppm. I’m not really sure If I’ve done something wrong, but any help would be appreciated.
Note: I am not currently experiencing any deficiencies, I just topped two of my plants and needed to water and wanted to test the run off.
