Nope, you are not wrong. But PH fluctuations cause damage faster in hydro systems, in turn making them harder to reverse if the problem persists. It's best to pick a place to stick close to and monitor and adjust accordingly. The point I was making is that a PH of 5.9 is common for hydroponics. Where as for soil, the PH would be higher.
