Made my own pH down, I dissolved 5g of food grade citric acid in a Litre of 7.2 tap water. 5ml of this brings a litre of water down by a pH of 0.9. I use water that's been stood in an open bottle for a day or so to remove chlorine and raise the temperature. So just done it and all my girls have had a good drink, fingers crossed for healthy plants.
