CANNA PK 13/14 is a concentrated phosphorus and potassium supplement dialled in for the peak of flowering. You add it to your nutrient solution during weeks 5–7 of bloom, it delivers the exact P and K ratio your plants are screaming for at that stage, and your flowers respond with denser structure, heavier weight, and better resin development. It works across hydroponics, coco, and soil — no medium gets left out.
Specifications
- Time your PK 13/14 window carefully — weeks 5–7 of flowering is the sweet spot. Start too early and you risk disrupting vegetative recovery; run it too late and the flowers won't have time to use it.
- Always adjust pH after adding PK 13/14 to your solution. It can shift your EC and pH, so check both before watering.
- Phase PK 13/14 out at least a week before your final flush to give plants a clean finish.

FAQ
What does CANNA PK 13/14 actually do?
PK 13/14 delivers a concentrated hit of phosphorus (13%) and potassium (14%) during the peak flowering stage. Phosphorus supports cell development and essential oil production, while potassium drives sugar production for denser, heavier flowers. It's a targeted supplement — not a base nutrient — designed to fill the PK demand spike that occurs at weeks 5–7 of bloom.
Can I use PK 13/14 with my existing Canna nutrients?
Yes. PK 13/14 is designed to work alongside the full Canna nutrient range. Add it to your existing nutrient solution during the flowering window — it doesn't replace your base A+B, it stacks on top of it.
Is PK 13/14 suitable for hydroponics?
Yes. PK 13/14 is fully compatible with hydroponics, coco, and soil growing systems. Whether you're running a recirculating DWC, a coco drain-to-waste, or a soil pot — you can slot it into your feed program during bloom.
Does PK 13/14 replace my base bloom nutrients?
No. PK 13/14 is a supplement, not a base nutrient. Keep running your base A+B throughout bloom and introduce PK 13/14 as an additive during weeks 5–7 only. Do not attempt to use it as a standalone bloom feed.
When should I stop using PK 13/14?
Phase it out at least one week before your final flush. Running PK 13/14 too close to harvest can leave residual phosphorus and potassium in your flowers, which affects taste and finish. End it early and let your plants clear properly before the final rinse.
Which size should I buy?
For a small personal grow or your first run with PK 13/14, the 250ml bottle is plenty to get through a full flowering cycle and see how your plants respond. The 1L suits regular growers running multiple plants per cycle, and the 5L is the value pick for larger-scale setups or anyone who's already locked PK 13/14 into their program.
