Canna PK 13/14 Bloom Booster - 1L Bottle

CANNA PK 13/14 1L: A One-Week Phosphorus and Potassium Push CANNA PK 13/14 is a mineral concentrate of phosphorus and potassium with no nitrogen at all. The US label reads 0-10-11, which is the same liquid Europe knows as 0-13-14. The difference is only the measuring convention, weight versus volume. The label rate is 0.2 fl oz per gallon, or 15 mL per 10 L, added once to a full reservoir of your normal feed. CANNA's direction is to run it for about one week, not the whole of flower. The timing that matters is roughly halfway through the flowering period, when the plant's call for phosphorus and potassium spikes. Phosphorus feeds cell formation in the developing flowers. Potassium drives the sugar production and water movement that fill them out. This is the 1 L bottle, which holds 33 fl oz and weighs about 2.65 lb full. Timing a PK Booster in the Middle of Flower Most growers mark the week on the calendar before flower even starts. On an eight-week cultivar that usually lands around weeks five and six, and a shorter or longer cultivar shifts the window with it. Shake the bottle, add it to the base feed you are already running, and check pH as you normally would. When the week is over, it comes back out and the plants return to their regular schedule. More is not better here. Stretching it across several weeks or stacking extra doses risks salt build-up in the root zone. CANNA pairs it with CANNABOOST Accelerator, which supplies the energy side of flowering while this bottle supplies the minerals. It slots into CANNA's grow schedules for soil, coco and hydro alike. A single bottle stretches a long way at such a low rate, so it suits tents and small rooms. Larger operations will find the jerrycan and drum sizes on the bulk listing more practical. Store it sealed in a dark spot, away from heat and frost. Key Features 0-10-11 mineral concentrate: Pure phosphorus and potassium with no nitrogen, labelled 0-13-14 in Europe. Low label rate: A fifth of a fluid ounce per gallon of feed, or 15 mL per 10 L. One-week application: Added once, at roughly the midpoint of flower, then removed from the program. Pairs with CANNABOOST: CANNA runs the two together so the plant has the energy to use the extra minerals. Works across CANNA lines: Fits into CANNA grow schedules for soil, coco and hydroponic systems. 1 L bottle: A compact size for tents and small rooms using it once per cycle.
