I'm guessing your in wales??? Looks like we have the same water PH roughly, think I'm going to buy that PH down made with phosphoric acid and see if my soil PH reduces as well (I like the fact my soil says "made for acidic soil loving plants)tap water here ie ph8 when i gave it vita link grow they dropped the ph to 3.2 fucked me for a while. mostly organic now and i dont ph. seems a lot easier.
