pk 13/14 little confused now, lol

HI guys, gals

Thankyou to Widow Maker and Potroast for replies, though im a little confused now . Ive used Canna vega and Canna flores, my plants look beautiful. So im halfway through week 3 of flower( 4th week in total under the hps, 1 week veggin, 3rd week flower) On the canna pk13/14 bottle it says " add pk 13/14 once; 3 weeks before harvesting blah blah... Add this mixture for 3-6 days.mmmm. So then does that mean that i need to add the pk every day for 3-6 days or just 1 time at the water change at the begining of the week and then no more? God knows! but then i reckon someone else might know as well. so please help me out.. cheers alot.

i think it is add once to your res,for one week only three weeks before you rip them?,but someone said on a post ,that the directions have changed and it no longer mentions the three week bit?,but my bottle does so i added some today,but lower than the amounts canna say to use,in fact i find i use most nutes and additives lower,than what canna say,but i use d,w,c so it may be different for other folk.,i change nutes during the grow,as it gives them a bit of a change,but at present in canna mode,so hope the stuff does what it says??

easy guys a few questions and thoughts i have been using canna cocco and using canna A and B cannazyme and rizortonic along with canna boost through my flowering stage, all as guided on the canna web sight you where talking about pk 13/14 i have used it in a few grows 1 time used it for a week 3 weeks into flower and 1 time 3 weeks from harvest and i can say the 3 weeks into seems to work better i have also made the mistake of using it for one watering seasion in week three and that was a waist if your using dwc or hydroponics i recond that would be right because you dont change your water every water eh ( sorry rambling ) any way my question:

has anyone used it @ the 3 week afterthe start AND 3 weeks from harvest? and if so what was the results like did it make any significant diference?

i sent the above question to canna thenselves and got the following reply....

Hi Mr floaty,

We advice in general PK 13/14 in week 5 in a Blooming period of 9 weeks. Other Plants we adjust this of the total. (ex. week 10 for een period of 18 weeks crop).
We increase the EC in week 5 with 0,1-0,2 EC above the regular Canna Flores. We apply it for 1 week.

If plants stay green and soft you may apply it for a longer period. But when the leaves start to burn at the tips or the borders, stop applying the PK.. May be you should decrease the EC in general.

I hope I answered your question with this reply.
Good Luck

saying that i have done what it said on the pack i used at full strength for 1 week in the 3 week of flower i have also just used it
for half a week 3 weeks befor harvest or there abouts but stopped when the leaves started burning then used plain water for the following 2 waters and then back on usual full feeding with no ill effects, going to start flushing for in a weeks time pic below...
let us no what ya think........

Hi there, this same query had me stumped for a while but after reading a few forums i have finally sussed what the hell canna are on about on the back of there container.I believe they want you to add 15 ml of pk13/14 to every 10 ls that u have in your nutrient tank already,(3 weeks before the end of harvest) keep this nutrient feeding plants for 3 to 6 days before replacing the nutrient back to it original dillutions.
About to add mine now for 1st time so will find out if i am right or not in 3 - 4weeks lolps i am using pebbles and recirculatary hydroponic system.
regards and any advice welcomed...Apophisgy

Hi just looked at when i posted this thread.. oct 2006.. i'd just started growing then, iv'e learnt to put my pk 13/14 in on week 5 , 15 ml to 10 litres and if i have to top up in the week i just chuck 5 ml in..easy with the canna nutes there shit hot but very concentrated and if your in a hard water area dont touch the canna aqua..im talkin hydro of course...cheers ta ta

I hit my plants with PK13-14 halfway through week 4 (growing in coco) due to the fact that I use boost which means sometimes theyre ready to harvest in the middle of week 7 (depending on the strain) and I like to give them 3 solid weeks of no pharmaceuticals to clean out whats in the stems.

ps mrfloaty, thats a mighty fine looking tree you got there.

so would this apply to a soil grow also?

The timing issue is for all mediums. The time frame I think, is not so much about the medium but more about the plant structure.

In the information its kinda confusing, one part saying week 5, and the other reference saying 3 to 4 weeks before harvest. 3 to 4 weeks before harvest is a bit of a guessing game as is not until like week 7 that you will know whether the bud is going to be ready. Could be end of week 7, end of week 8 or even into week 9 depending on the plant. So 3 to 4 weeks could in those situations mean either week 4, 5 or 6.

I think the point is that the PK13-14 is straight pharmaceutical phosporous and potassium. It takes about 3 weeks for a plant to use up all the nutrient in its stem. The idea I think is to allow 3 weeks from the time you last fed them PK13-14 till when you havest your plants.

Also since it is pharmaceutical I think they are trying to say dont feed plants that aren't developed enough. Which is why I hit mine at 4.5 weeks to 5.5. The boost causes faster development and sometimes faster harvest maturity.

cheers jones for the comment on mi minni tree i used full strength pk 13/14 on it in the 3 week for a week then for about 4-5 days in the 3 week befor turned a few fan leaves a little off coulour but nothing i would go crying to mum about hehe, i got around 8oz off that bush in cocco using canna cocco nuts from there web sight with 400w hps light, room size 2 ft x 2ft x 4ft a little small for some strains but gets plenty of nice quality but out of it.

as for the pk13/14 try full strength when you you have little buds forming this will fatten then out and full then up that what it basicly does check the canna web sight out......

thanks dude for the comment on mi pic from my previuse thread i used pk 13/14 in 3 week for a week then for 4-5 days 3 weeks befor harvest it got me 6oz cured from 4oow hps in 2ft x ft 2 ft x 4 ft canna cocco and all the respective nuts not much in it check the picfor budsize haha peace........

Could anyone provide a picture reference to how developed the plants should look when they're ready for the 13/14? many thanks

cannot find any pic in any of my photo albums of plant pics but saying that, it depends if you use it week 3 after start of flower or 3 weeks befor harvest, to know more about pk 13.14 check the link.....

http://www.canna-uk.com/pk_13_14

holla let me no when you plan to use it will have pics of 3 weeks befor havest but i recomend using it 3 weeks into flower and a little 3 weeks befor havest or untill your plant says no more ie nut burn
if there is any further info holla and will try and help.....

I used to use that 13/14 PK but it wasn't really the right fit. I read up on it and Advanced Nutrients said that this wasn't the right ratio. They use a 9/18 in their Hammerhead, so I decided to give that a try.

Right away I noticed the plants were a lot happier on the 9/18 than they had been on the 13/14. I've seen it a lot of other places too, people saying that the bloom enhancers have too much phosphorus and not enough potassium.

So yeah, anyway if your plants aren't doing as well as they ought to be and you're using PK 13/14 you might want to check out Hammerhead. Might be a fix for you the way it was for me.

cheers dude i got about 5-6oz dry off that baby........

Hey I was reading the pk bottle today and it seems you run this shit at the rate of water add pk till ec of 1.2 is achived and no nute nutes
what do ya think any one ran straight pk?

pk13/14 is bollox I got it next to same pheno/straine with just its bloom and the one with no pk is way better looking with bigger buds,product IMO is bollox

nice lady you got there. i used it the last 3 days before a water change. what it is basically used for is to simulate a drought condition in the plant making the plant produce flowers sooner than it normally would for a bigger yield if used at the right time. usually at the end of week three or week four depending on the strain. then back to regular feeding with an addition of a bloom enhancer or finishing additive. I love MOAB (Mothers of all Blooms) in which I think has worked better for me than a shooting powder, kool bloom, overdrive etc. etc.( www.atami.com ) happy growing buddy

@ Knowboddy. Have you ever tried MOAB. Mothers of all Blooms. Its 1-52-32. I have had great outcomes with it. You use it first week of Bloom and then the last 2-3 weeks. I can really see a difference with all my strains
