Product description
Canna PK 13/14 500 ml – phosphorus and potassium kick for mid-flower
You only need PK 13/14 for about a week per run, so for a home tent there is little point in buying a big can. The 500 ml bottle covers that one important week in flower for a long time, and it is the easy way to try a dedicated PK booster for the first time.
Canna PK 13/14 is a concentrated phosphorus and potassium supplement, NPK 0-13-14. Given at the right moment, roughly halfway through bloom, it supports the build-up of large flower clusters and dense fruit.
How many runs is that?
At the maximum of 1.5 ml per litre, 500 ml treats about 330 L of nutrient solution. If you feed a single tent from a 50 L tank, one PK week uses only around 75 ml, so the bottle lasts for several runs.
Timing and dosing
Add it to your normal feed for about seven days at 50–60% of the flowering period. In an 8-week variety that means around week 5 to 6. Small tanks make precise dosing tricky: with a 10 L watering can you need 15 ml, which is easiest to measure with a syringe or small measuring cup.
Potassium pulls the pH down, so check it after mixing. If leaves start showing signs of calcium or magnesium shortage, lower the dose.
