Advanced Nutrients pH Up 0-0-38 (57 L): High-Concentration pH Adjuster
pH Up is the workhorse you reach for when reservoir pH drops below the uptake window and plants start showing micro lockout symptoms. The 0-0-38 NPK is potassium hydroxide — the chemistry that raises pH cleanly without dragging in chloride, sodium, or other ions that mess up nutrient availability. That distinction matters because a lot of generic pH up products use sodium or chloride compounds, and over time those accumulate in recirculating reservoirs and cause secondary problems. Potassium hydroxide doesn't. It also means the only thing pH Up adds to your solution is potassium, which most flowering plants are already pulling at high rates.
pH Lockout Prevention Across DWC, Coco, NFT, and Rockwool
What you should see in the room with consistent pH correction is no trace lockouts. When pH drifts low, the micros lock out first — iron, manganese, zinc — and by the time you see the leaf symptoms you're already a few days behind. Holding pH in the 5.5-6.3 uptake window is the simplest way to protect yield, and a high-concentration adjuster like this one means you're using less product per correction. The 57 L size is the commercial volume for facilities where pH correction is a regular maintenance step across multiple reservoirs. It runs in DWC, NFT, rockwool, and coco without fouling reservoir chemistry or interfering with chelated nutrients in solution.
Key Features
- 0-0-38 Potassium Hydroxide: Raises pH cleanly without chloride, sodium, or other incompatible ions that accumulate in recirculating reservoirs.
- High Concentration: Concentrated formula needs a smaller dose per pH unit, cutting the potassium added per correction.
- Recirculating System Compatible: Runs cleanly in DWC, NFT, rockwool, and coco without fouling reservoir chemistry or chelated nutrients.
- Nutrient Lockout Prevention: Holding pH in the optimal range keeps micros and macros bioavailable at the root zone.
- 57 L for Commercial Use: Large format cuts restocking frequency for facilities where pH correction is a regular maintenance step.
