Not sure if its just me or others have same low ph problem with ocean forest. Every time the runoff ph is really low like 4.5 - 5.5 after i feed or water ph at 6.5. I heard a lot of ppl saying dont need to ph if grow in soil, the soil has ph buffer, so no need to ph or check runoff ph. So i am kinda confused here. Can someone explain it to me? Thanks

Add some dolomite lime to the soil to help raise the pH. You don’t need much. Maybe a teaspoon per gallon of pot size.
