i was reading somewhere the other day someone talking about different ph for plain water vs your feed ph. is this true? i’ve always gave plain water at or very close to the same ph as my feed. i ph my feed anywhere from 5.8-6.2. almost always have to use ph down usually start at 6.4-6.7. every now and again i’ll add roots, and protekt to my plain water day and i do ph this to the same range as my full feed water as there is technically feed in it. but the days i give plain water i always ph down to 6.0 hardly ever lower. how does everyone else do this? can’t find much info around.. am i delivering my 100% plain water at the wrong ranges? it’s tap water and my tap water sits at like 8.1 ph 230-270 ppms. i’m in promix cut with perlite. thanks
