Hi all, I'm considering using some canna pk 13/14 for this crop (never used before).

From what i understand i add it to the nutrients 3 weeks from the end of the crop for 1 week and then just flush with ph 5.8 water as normal for the last few weeks to get rid of those chemical tastes.
Has anyone here actually used it?, If so does it really make much difference?, Has anyone tried using it for longer than 1 week & if so what were the results?, Has anyone tried using it at any other times except for 3 weeks from the end & if so what were the results?

Any info would be helpful, Thankyou all.

Loads of info

It does what it says on the can and then some too.

But you must ONLY use it as per directions,don't even consider fucking about with any 'hot tips' a mate may have told you.I've used it for years,never had to look for anything better,but since joining UK420 I myself am gonna wean myself off useing chems and get some dirt under me nails,ya dig?




Edit:I have actually used it in a compost grow with stonking results.

Could some one tell us if Hesi phosphorus Plus is the same type of product.
I have a bottle and was wondering if it can be used as a flower booster.
thanks

I browsed across an old OG post the other day with a collection of comments about PK 13/14.. might be some useful info in there for someone,

Canna PK13/14

(Dogbert) sets the standard. This one works!! WARNING – watch out! You can burn your babies with it if you are not careful. A must use additive. The bottle recommends to add one dose 4 weeks before harvest. Many users recommend adding a half strength dose every week for the last 4 weeks.

(BiGgErBud) I use the complete Canna range, Rhizotonic, Cannazym, vege..... flores, PK 13-14. Great products!! only advice I would give is to use PK at half strength from week 4 to flush as it's strong as Bramski and now Dogbert have found out!

….then PK13-14 last 4 weeks helps buds pack on weight.

(Bramski) I have searched the net for info on PK 13/14…

”PK 13-14 is a pure potassium and phosphorous mix that stimulates the plants natural sugar production to such a point where essential oils are literally dripping from the plant. PK 13-14 is derived from potash and all the outdoor freaks would know how beneficial potash is for tightening up those colas. “

I have played a little with this product and was astonished by the increased flower development and improved flower set on the plant especially with such economical dilution rates.

(budmonster) according to the guy at the hydro shop pk 13/14 is the same as liquid potash which sells for a 1/4 of the price.. It makes you wonder! In other words, any product that is really high in Potassium and Phosphorous, if applied at the correct time during flower, will cause swelling of the fruit/flower/bud.

So maybe even just maxxing out the normal flower nutrient at week 3-4 of flower would work just as well as some of these expensive concentrated bloom additives, but a word of warning, you will get a more nutrient taste in the bud if you use pk-13/14 (or were to max out the flower nutes.

This is why I really like a locally made product for using in the flush stage called Ozi-tonic. It’s a 100% organic product based on a beeswax formula and gives your hydro buds a lovely almost outdoor (organic, orgasmic!) sweet smell!

(Dutch master) ...always check your Ph and EC (ppm) AFTER you added PK13-14. You will see there will be a substantial (increase) in the salts of the solution you are using.

(haze5) I use bio nova's BN p-k 13+14
This product contains 13% p2o5 and 14% k2o. phosphor makes for the development of a healthy, extensive root system and for exuberant flowering. Potassium prompts the flowering of the plant and the flowering potency. The combination of these two materials in a bio-mineral shape can indeed be called a super-bloomer. For this reason, this directly absorbable fert is essential to the flowering stage of any crop.
P-K 13 + 14 should be used in addition when using BN hydro or soil super mix.

Dosage
1st week of flowering :25ml/100l
2nd week of flowering :50ml/100l
3rd week of flowering :75ml/100l
4th week of flowering until flush :125ml/100l

(HiLlBiLlY BuDmUnChEr) At 3 weeks from harvest I give the plants Canna ‘PK 13-14’ in with their nutes and this makes them fatten up in the bud department….it is very easy 2 f*ck up with this stuff in hydro. Only use it once to a full tank and NOT in your top up water or you'll get nute burn like Bramski and I did

(oldpink) PK 13/14 is mixed into your nutrients at 15ml per 10L. Mix it into your normal nute mix for 1 week only then back to your normal nutrient mix. pH. will raise as well as your C.F. reading. PK 13/14 is used 3 weeks before harvest

(Unregistered) I have revised my usage of Pk 13/14 after 6 or 7 test crops. Im using it every week now at the rate of 1ml per liter of tank soln. I have found greater assimilation and benefit with the lower rate of addition over a greater period, from around week 2 to week 6 of flowering."

I am so sorry guys,still having major probs wiv me pc

This is my first grow,and i've just finished using PK 13-14[thanks Rockster ].

It's a soil grow,no hydro for me yet but it definitely did do something.

I used it for 1 week at the standard amount,which was 3 waterings for my AK's and they've grown much longer white pistils since and i've had to tie a few Cola's up as they're too heavy for the stems now[i'm not complaining mind ].

I've no idea if the same rules apply to a soil grow as hydro for it's use,so i erred on the safe side and did what it said.

There's still loads left too,as i've stopped using it now and i'm on Canna terra florres for the final stretch so plenty left for the next grows too.
