Best times to use a PK 13/14

Hi everyone, I have been reading a lot about how cannabis likes lower P levels in flower with occasional spikes to boost flowering and I was wondering how to best do this.

I am going to be trying out canna coco a&b with the pk 13/14 a couple times during flower. Theyre chart says to only use it once, but from what Ive seen it might be better to use multiple times during different flowering stages.

Im thinking of using it at week 3 and week 6 on a 9 week strain (8 weeks nutes w/ 1 week flush) for 3-4 days only.

If anyone else has tried using spikes of P instead of just increasing overall levels in flower I would love to know how you did it. Im trying to find the best way to try this before I start experimenting. Thanks everyone!

When I was running Canna products (still use the Boost and pk 13/14 in my program now) in Canna coco I ran the A&B @ 8ml wks 1-7, Boost @ 4ml wks 2-7 (9-10 week strain) and ran the pk 13/14 @ 2ml wks 2-4 bumped it up to 6ml wks 5-6 and back down to 2ml wk 7 (9-10 wk strain). GUARANTEED FROST!! I flush for 14-21 days with plain acclimated pH'd water.

Im in soil now and still run the Boost all the way thru flower but ONLY run the pk 13/14 in wks 5-6.

This run I used Moab/Cannaboost in week 2 and day 28 of flowering. I plan to hit them one more time with the Moab/Cannaboost combo around day 38-42. I have been reading desert squirrels threads and trying to see when he does his boosts.

I always thought it was desert squirrel as in squirrel from the desert, so it's dessert squirrel as in he's a squirrel that likes pies/cakes/cookies? lol

This is an interesting question. Canna recommends hitting them once in week 3, but almost every other manufacturer's schedule includes some form of PK boost throughout. I'd be very interested to see any kind of quantitative testing showing how much additional PK levels affect yields. Of course, the base flowering nutrient is full of both of these, as well, so there remains the question of which (base or boost) is best to elevate at the point they need it the most.

Google "myth of high P", really informative on the respective merits of P vs K for bloom boosts.

We are getting sold a bunch of P that we do not actually need.

I remember reading an email from dyna bloom in a thread somewhere that was explaining their very high P nutes. It essentially said that while plants dont really need or even like extremely high P, the consumer (being growers who shop at hydro stores) wanted high P formulas so they were going to supply them. I thought it was funny

this tray i did it like canna says to give it(day 20 in my case), from my best understanding you give it when the plants stop their stretch at 6ml a gal and overnight they pretty much triched/resined up and became alot more sticky and more aroma too,,,,i'm gonna runa res like that for 10-14days and then down to 2ml a gal till flush, im using all canna aqua, plus boost @ 12 ml a gal too, healthiest plants i have had in quite awhile,,,, i 12/12 on 5/13 and they are covered in trichs with thick bud development with ((this pic is on day 25))) cola development beginning to....yellowed leaf area are ruby red's, rest are millenium and a few bubblegums too
