In the course of all of my research into marijuana growing it seemed that the suggestion for ph of water to give your plants was to have it about 6.5ph. However, recently I have found a lot of people saying that it doesn't matter what the ph of the water is as the soil will buffer it and make it right for you. This has left me confused, so I would appreciate some experienced growers opinions on the subject. So; Should water ph be about 6.5? or Can it be anything, as the soil will adjust it to the ph of the soil?
