No adjusting just straight from the tap. I assume it gets higher in alkalinity the longer I let it sit out. Just straight from the tap I think it's around 7.5 ph. I was having more issues when I was lowering my water ph than leaving it be. I suppose a higher alkalinity is preferable to a lower ph in soil. Next time I'll be using some dolomite lime as a buffer and I might whip up a batch of Subcool's Super Soil. I'm hoping to get paid soon so I can get my meters and some new beans for next time. I believe the FFOF has a ph buffer that wears off after about five weeks so I need to get the ball rolling on that.
