CANNA PK 13/14 is a concentrated phosphorus-potassium supplement by Canna, designed for administration at peak flowering. Its high PK ratio (13-14) triggers a massive influx of P and K to flowering sites, amplifying bud formation and accelerating ripening.

Phosphorus supports cellular energy (ATP) and sugar biosynthesis in flowers, while potassium regulates ion exchange, improves turgidity and strengthens stress resistance. Together they produce more compact, dense, resin-rich flowers.

Use once in mid-bloom (week 5-6 of 8), for 1–2 weeks maximum. Compatible with all substrates. Dosage: 1.5 ml/L. Available in 250 ml, 500 ml, 1 L and 5 L.
