PH down advice

I'm using irrigation water like I have every year, but this year is s REALLY low snow pack year. My irrigation comes from snow pack early and then glacier melt.. I bought a pretty decent quality PH meter and my water is pretty consistently measuring at 7.0-7.1. I bought two food grade 55 gallon drums for watering, what recommendations would you give for lowering the PH?

Earth juice natural down works great. Botanicare down also works good too. Ive used both with the same results

Best to gradually work it down?
6.5?

weak ferts dosage will lower it. doesn't really take much at all.

none at all in soil outside.

I will agree with TWS good hot soil will buffer down ph so no need to use ph down when you have ph 7

no need to use ph down in soil id leave it alone if you not getting any problems cos you only create one if you start to mess with ph levels
