1. I would NEVER use distilled water UNLESS it has then be reverse osmosised afterwards.

Anyhow, DO NOT water with pH of 3!!!!

Simply buffer it up back to the 6.0 - 7.0 range.
HARDDON Reviewed by HARDDON on . PH level Ok I mixed a litle over a teaspoon of Neptuen's Fish Fert )pictured) with a gallon of dist. water and used a ph test from my hydro setup and it came back like 3, wtf? Will this hurt my plants? Or is the test no good this way? Thanks Much, sorry if this is a stupid question, I looked before I asked. Rating: 5
