AsNoriuanswered grow question a month ago How you test soil ph ??? With cheap 5 $ meters or you bought something expensive, like triple blulab probe or something.
People check run off, but even then you have to know how to test. Dont take first run off, take middle or last, colect it to clean plate and so on, many things.
Flushing is for coco or hydro, in soil you never do this shit. Fact.
