MILLS pH FLOWER 1 LITRE

Description

Mills pH Flower 1 Litre is a professional-grade pH adjustment solution from Mills Nutrients, formulated to lower the pH of nutrient solutions during the flowering stage of plant growth. We have been recommending Mills pH management products to UK growers since 2017 as precise, high-purity alternatives to generic pH-down solutions, with the quality control and concentration consistency that professional growers demand from every product in their nutrient room.

Why pH Management Is Critical During the Flowering Stage

Maintaining the correct pH in your nutrient solution is arguably the single most important variable in hydroponic and coco cultivation. In coco and hydroponic systems, the target pH window of 5.8–6.2 determines which nutrients are soluble and plant-available at any given moment — drift above 6.5 and iron, manganese, and zinc become increasingly unavailable, causing the interveinal chlorosis and poor flower development that many growers mistake for nutrient deficiencies. During flowering, the stakes are even higher because plants are drawing on their full nutrient complement simultaneously to support both vegetative maintenance and the rapid metabolic demands of flower development. Mills pH Flower is a phosphoric acid based formulation calibrated for precise dose-response in nutrient solutions, making it easy to make accurate small adjustments without overshooting the target pH. The 1-litre bottle provides a generous supply for numerous pH adjustment sessions across multiple grows.

How to Use Mills pH Flower Correctly

Add pH Flower to your nutrient solution drop by drop while stirring and monitoring with a calibrated pH meter. Allow 30–60 seconds between additions for the solution to equilibrate before taking a reading, as pH changes slightly as the solution mixes fully. Target pH 5.8–6.0 for coco and hydroponics, and 6.0–6.2 for soil and peat-based media. Calibrate your pH meter before each use using pH 4 and pH 7 buffer solutions for accurate readings. Store pH Flower in its original container, tightly sealed, away from light and heat. As with all acid solutions, wear gloves and eye protection when handling concentrated pH adjustment products.

Pair Mills pH Flower with Mills pH Up, a calibrated digital pH meter, and pH buffer calibration solutions for a complete, accurate pH management setup. Browse our full Mills nutrients range and pH management accessories for the complete grow room chemistry toolkit.
