Mills PH - 1 l Flower
Mills pH- 1 litre is the highly concentrated pH adjuster from Mills Nutrients based on 59% phosphoric acid.

The extreme concentration ensures 1 litre lasts exceptionally long.
Mills pH- 1 Litre – Concentrated Phosphoric Acid pH Adjuster
The pH of your nutrient solution determines whether plants can actually absorb what you feed them. A pH that is too high renders essential elements unavailable regardless of fertiliser input. Mills pH- from Mills is a highly concentrated 59% phosphoric acid solution that lowers pH quickly and precisely.
Why Phosphoric Acid?
Mills deliberately chose phosphoric acid as the active ingredient for pH-. Unlike nitric or sulphuric acid, phosphoric acid leaves no harmful residues and contributes slightly to phosphorus availability. This makes it suitable for use throughout the entire growing cycle.
Application and Dosage
Add Mills pH- drop by drop after incorporating all other products. Measure pH after each addition. Target 5.5-6.0 for hydro and 6.0-6.5 for soil. In most situations, pH needs to be lowered after adding Mills Basis A&B and additives. Keep Mills pH+ available for the rare cases where pH drops too low.

Why does Mills use phosphoric acid in pH-?
Phosphoric acid is a mild yet effective pH adjuster that leaves no harmful residues in the nutrient solution. It additionally contributes slightly to phosphorus availability, which benefits the plant.
Should I adjust pH before or after adding nutrients?
Always adjust pH after adding all nutrients and additives. Fertilisers influence pH, so adjusting beforehand is ineffective. Add Basis A&B and other products first, measure pH, then correct with pH- or pH+.
How much Mills pH- do I need per litre of water?
Mills pH- is extremely concentrated (59% phosphoric acid). Always add drop by drop and measure after each addition. The exact amount varies depending on your source water and the buffering capacity of your nutrient solution.
