The DEFINATIVE Canna PK13/14 usage guide

This stuff is doing my ****ing head in! I've been using Canna PK13/14 in weeks 3 and 5 of 12/12 with an eight week strain. Now it seems I should only use it in week 5...or week 6...or weeks 3,4 AND 5!

My growing is sooooo simple - eight weeks of 12/12 then chop. Canna's guide is for UP TO twelve weeks of 12/12. WTF should I be doing with this PK13/14? Chuck it in the bin?...sell it on Ebay?

I think you're going to get a wide range of responses. Not sure if there is any best way.

That said, I have noticed that using pk too early can cause slightly strange bud formations. Next time I'm going to just use it a couple times from weeks 6-7 on 10 week strains, after everything is forming up nicely.

Curious to see what others have to say.

P/K 13/14 isn't necessarily the correct ratio ..... Advanced Nutrients did a test of bud chemistry and found in finished bud the P/K was 1 part P to 2 of K

I've been using Vitalink buddy which is 9/18 P/K and got some lovely results

In coco I start at day 21, 1/2 strength, 28 - 39 full strength, 40 - 50 GH Ripen (P/K with added CalMag) only, then 8 days flush, 2 of water and recently got buds like this



They smoke a treat

9/18 is actually 4.5 / 18 btw...

13/14 is actually 6.5/14

so pk 13/14 is already 1:2 ratio...

Hey Harry. I have been using pk 13-14 for about 2 years and love it. I follow pretty much what you said, weeks 3 and 5. Sometimes I will continue to give them some into week 6. With your 8 weeks of 12/12 I would say stick with week 3 and week 5. I dont know why nobody can agree on a definative dosage for pk 13-14. I like how I do it. I think it helps to deprive them of the extra P and K for a while. I wanna make them want it. Many people give pk13/14 all the way through flower. I disagree with this and feel its a waste of nutrients. Stick with weeks 3 and 5 bro and you will be fine, dont get frazzled. Good luck.

The way i was taught was that flowering plants (60 to 70 day cycle needs a P & K boost from days 37 to 45 . at which time you lower you dosage on the base nutes to make up the difference in your EC & to start the lower dosage of nutes . 45 to 52 days i give my regular nutes @ 75% less then I flush till harvest .
this is how i was taught to use a PK boost ... it works for me . I also don't use the canna PK 13/14 i use general hydro's Hydroplex , its more concentrated & it has a little more iron that coco lacks .

I use the nute schedule that Bush Dr uses and it's wicked, I've seen improvements all around including, vigor, bud size and density, and most importantly aroma/taste. You guys want some zero BS growing advise? Then go pick Bush Dr's brain.

Bush, that plant pic is kickass, the hues are amazing. I'll have to pop them Orange Hill seeds asap, hopefully before the years out.

:jawdrop:

PK 13/14 is not a 1:2 ratio, man.


Use PK13/14 only with Canna line nutrients for best results.
Use PK13/14 in week three or four for quick flower, 8 week, strains.
Use PK13/14 in late week four, into week five for longer strains.
Use PK13/14 for three to five weeks, mid flower, for outdoor use.

As stated above, it is best to use the Canna PK13/14 along with the Canna A/B, Rhizo, Zym, and Boost. Canna Coco line was not designed for use with any other products other than Coco line products throughout cycles. This can result in undesirable outcomes as well as poor growth performance. This is the complete set-up from head to toe. Canna has taken care of the hard work.
Visit the Canna site often.
Check out the Canna Talk magazine articles they post up.
Valuable information.

Remember... Canna is not Advanced Nutrients or HGE.
They're like apples and oranges, they're both fruits, but you can't eat 'em the same way.

I'd like to see the studies by Advanced Nutrients that are bashing Canna's PK13/14. Of course AN is gonna' run some wacky test to try and discredit the product/research the Canna team has introduced to the industry. That's just advertising.
On my days off, I'll burn down some PTW and go hit up the shops in my area that can't even sell Canna products. I'll ask them about AN or GHE and all I get for an answer is "It's way better than Canna." or "It's the same as Canna, same scientists." Then when I ask these guys what makes it better than Canna, they just say something like "It just is" These guys don't even know they're product.
As far as I've noticed, Canna won't even sell their products to a vendor that is not learned in Canna tech.
Most vendors attitudes will change severely after inquiring about Canna.
So yea, a little rant, but I feel like all that AN, GHE crap is propaganda/advertising.

COCO FEEDING SCHEDULE

Day 1 - 7 Plant Magic Grow, full strength, pH 5.8
Day 6 - 20 Plant Magic Bloom, full strength, pH 6.2
Day 21 -39 Plant Magic Bloom, reducing strength from full to 1/2 by end of period, P/K starting at 1/4 strength increasing to full strength by day 30, pH 6.2
Day 40 - 49 Ripen, full strength, pH 5.8, Molasses given 3 times during this period
Day 50 - 56/58 Plant Magic Flush, no pH adjustment
Day 56/58 - 58/60 Water, no pH adjustment

If you can't get Plant Magic then Hesi will do

I'm currently trying the Plant Magic P/K, not sure of exact P/K, I'll post that later, but very impressed with results

All this is based on a Run To Waste set up, with 5% run off (it used to be 10% but fine tuning has proved 5% is better)

I use Plant Magic coco, which IMHO is better than Canna, although I use Canna now and again, the PM coco is milled to a finer more consistent texture ..... it just feels better .... it does give better results

Feeding is done by drippers, 3 feeds/cycle at the start increasing to 5 as the flowers fill out

Small rez, with air curtain in to increase dissolved oxygen to 100%, fresh water and feed made up every day and pH'd just before first feed

Reasoning for RTW -
1 If the plant didn't want the remaining feed 1st time, why should it want it after it's been through the media?

2 Fresh nutes every day mean I know exactly what they're being fed (not so with recirculating)

3 No used solution being recycled so chances of spreading pythium or other infection from plant to plant are almost nil

I've found this reduces flowering time from 10 weeks down to 8 or so and produces big buds with lots of flavour



It'll vary slightly but I aim for this most of the time

Hope it's appreciated

Finish it and get canadian xpress superior potash, thats what i did. Much better. Dont use any canna products now, gone right off them after some research. Weak nutes and just about average. Apart from canna boost which is allright and rhizotonic which i like if not in a hydro setup.

See what I mean? Sooo many ways to do things. I have to say I'm usually pleased with my results but just like everyone else, I'm always up for squeezing another few grams out of my system.
I think for now I'm gonna stick to using it during weeks 3&5 of my 56 day strain...unless someone nows better?
