Some advice on pk13/14 please.

Wow, great stuff. Thank you. I knew that N would inhibit thc production but had no clue about the K doing the same thing. So I’ll run 4-6-8 from week 3 to week 5 then taper down the K to week 7 then drop everything, and begin flushing. I’m running all CANNA on a cheese that I like to take to 10 weeks. Thanks again.

I feed my plants the same nute right through veg and flower,with just two extras Big Bud and Pk 13/14 halved my feed though to 1.3 right through.Just Canna a/b Coco

I use it for years now ,but use at around 1.5 ml per ltr ,but I work with ec but with canna a/b that would take you to 1.1 ec has a guide .but deep on your water ec .But brilliant love watching the buds swell after PK ,try big bud instead of canna boost too a lot cheaper same results,at week 2 .I use PK at start week 5 for 7 days

Shit I've been using canna pk13/14 start of week 3/4 depending and finish end of week 6.
First week half strength on bottle
2nd week full strength
3rd week double

Man I'm guessn this is completly wrong

There's very little positive in running PK in containers. It's mostly for hydro were you can better control pH of the solution. Excess PK will only crash pH to the ground growing in containers.

Cannabis has low to moderate requierments for P and excess K is detrimental for potency.

That's my understanding as well. However cannabis will not only store P in the leaves but it will continue to readily up take it if supplemented. The plant translocates P to the flowers primarily for seed, doesn't matter if seed is or isn't present. Less is definitely more with Phosphorus. This is the main reason I don't commonly add phosphate to my No-Till. Instead I use a product called Mammoth P.

Is there any evidence that pk actually boosts weight if you're using a full profile nutrient?
