Description
A late-flower P and K hit for bigger, denser fruits and flowers
Canna PK 13/14 is a concentrated potassium and phosphorus supplement (NPK 0-13-14) added to your base nutrient for one short phase in the second half of bloom, when demand for these two elements peaks. It drives bigger, better-quality fruits and flowers and suits most substrates and hydroponic systems. Use it on its own — never stack it with a second PK booster, or you risk over-feeding and nutrient burn.
Key Benefits
- NPK 0-13-14 — high-strength potassium and phosphorus for peak bloom
- Bigger, denser flowers and fruits when paired with a base feed
- Compatible with most substrates and hydroponic systems
- Single-shot booster — no need to change the rest of your schedule
Undersized flowers in the final weeks of bloom
Even a well-fed plant produces underdeveloped flowers if it runs short of phosphorus and potassium during the final stretch. PK 13/14 tops up exactly these elements at the point of highest demand, without disturbing the rest of your feed.
How to Use
- All substrates and systems: 1.5ml per litre
- Timing: begin around 3 weeks before the end of flowering and use it for 3 to 6 days only
- Do not combine with any other PK booster, to avoid nutrient burn
