i used to feed mine with a ph of 4.0 going in.....never had a prob with those nutes. (earth juice) The soil buffered it to an acceptable range an plants ate it.
I'll post the same thing in this thread so you can read it again. Ph is everything that includes soil ph. If the soil ph is buffered you still need to ph the water unless your water only growing. In water only growing your soil is built up and micro organisms keep the soil buffered. Once you add sythetic chelated nutrients you kill the microbes that buffer the soil.
im not talking "grow mixes" that are made of peat moss perlite an lime , im talking soil.
Even peat moss is a buffer , it will stay in the 5.0 ish range without the lime to bring it up.
