Canna pH down 1L (bloom)

Keep flowering nutrients available with rock-steady pH

Canna pH Down (Bloom) is a professional phosphoric-acid-based pH reducer formulated for the flowering phase, when stable pH matters more than at any other stage. A concentrated dose keeps your nutrient solution in the range where feed stays uptakeable, helping prevent nutrient lockout and protecting bud development. It pairs with the Canna range but works with any feeding programme.

Key Benefits

• Bloom-specific formulation matched to flowering-stage nutrient demands
• Concentrated acid so small additions make a measurable pH change
• Helps prevent nutrient lockout caused by pH drift
• Keeps uptake consistent right through the flowering window
• Works with any nutrient line, not just Canna feeds

pH drifting out of range during flower?

Even a perfectly balanced feed becomes unavailable if pH drifts, showing as nutrient lockout, yellowing leaves and stalled buds in flower. Regular checks with Canna pH Down (Bloom) hold the solution in the correct band so the plant can actually take up what you feed it.

How to Use

• Always adjust after mixing nutrients, never before
• Check the solution with a reliable pH meter
• Add pH Down a little at a time, stirring and re-testing between additions
• Target range: around pH 5.5–6.2 for hydro/coco, 6.0–6.5 for soil (adjust to your crop)
• Re-check periodically, as solutions naturally drift over time
