pH Down – acid based pH control for soil and coco | Phosphate-free formula | Concentrated liquid for gentle, predictable adjustment

Description

What it is pH Down is an -acid based pH adjuster for soil and coco feeds. It lowers alkaline solution into the plant-ready range so nutrients stay dissolved and easier for roots and beneficial microbes to use. Why pH matters Most essential elements are best available within a fairly narrow band. Above that band, calcium, phosphorus, iron and others can bind or precipitate. Keeping feed in range limits lockout, steadies uptake and helps growth stay predictable from week to week. How it works A measured dose of pH Down shifts carbonate and bicarbonate alkalinity, bringing solution pH down gently and repeatably. In the root zone, a stable pH supports enzyme activity and a healthy microbiology, which in turn helps plants make use of the minerals you supply. FAQ What does pH Down contain A blend of acids in water. It is phosphate free and not potassium hydroxide based. When should I add it in my mixing order Always after nutrients and additives. pH can shift as components dissolve, so set pH last for the most accurate reading. How much should I add per litre There is no single dose that fits every water source. Start very small, mix well, wait 1 – 2 minutes and re-test. Hard water usually needs more than soft or reverse-osmosis water. What target pH should I use Soil 6.0 – 6.5. Coco 5.7 – 6.0. Staying within the band is more important than hitting an exact figure. Does it improve nutrient availability Yes. Keeping pH in range helps calcium, phosphorus, iron and other elements remain soluble and plant-ready, reducing the risk of lockout. Will it harm beneficial microbes Used correctly to reach the target range, stable pH supports predictable microbial activity around roots. Can I use it in a reservoir or only for hand-watering Both. Add in small amounts with good circulation, then re-measure after 1 – 2 minutes. My pH drifts after a few hours. Is that normal Some drift is normal as the solution equilibrates and plants or microbes use nutrients. Re-check before each watering and make small corrections as needed.
