Cana nutes advise/ recommendations

Hi Guy's I'm 5 weeks into flowering my first grow, and They have come out well, with all the reading I have been doing. But now looking onto the next batch and what I can learn more.

I have grown using the Canna Nutes and Via the canna grow guide on the web. In a 4 pot wilma with coco choir

I have seen that some people are Using Pk13/14 more than once in the grow. The canna guide says to use it once 3 weeks before flower, Can it be used more than one dose? if so When do you start using it, how much do you use, and when do you stop using it.

Also thinking of going to Bud XL for the next grow, is there any other things you would recommend changing for the next grow nute wise?

Many Thanks
A Happy Grower

i grow in coco but hand watered.


here is a typical 8 week strain regime:

i use a+b at full strength for the first 3 weeks of 12/12 then half strength until week 7
rhizotonic for the veg and transplanting
pk13/14 for 5 days in week 3
boost from week 2-7
bloombastic from atami from week 5-7 this is the best booster i have used by some way but it is thick and sludgy so i would not recommend it for a wilma system.


pk13/14 is a very strong and can cause major salt build up if you use it too much, i would recommend using it less rather than more. you don't want all the fan leaves falling off prematurely.

Ah right, that makes sense, Thats why I wanted to check, there's good and bad info out there.
So your using Boost and this Bloombastic together I was thinking swapping out the boost for the Bud xl? Could I run boost and Bud Xl then?

Hey, im using the canna aqua line, in coco, (i know but im loving it. )

The bud xl and pk 13/14 are kinda the same thing if i remember correct. So go easy if you do decide to use them both.

i use the pk 13/14 from week 3 of flower through to flush, at 1.5ml per lt(worked up to). Loving it. Thats in soil sorry. Am just starting flower with some coco clones and i intend to use it in the same way, just start of in week 3 at half a ml then work them up.

There are a few threads discussing the use of pk13/14 and when to use it. I also recall canna telling someone that there bottle says use it one week where as they will tell you to use it for a good 3 weeks. Between week 4-6, then also growell have a feed chart where they use it from 4 weeks before chop, then stop it in the last week for the 'flush'.

The only thing i dont use from canna is the ripoff boost. (Make me own) , so couldnt comment on when to use that.

op, if you aint got it rhizo is a very nice product. Dose just as it says and is a nice foliar i find.

i have had 3 bottles of canna pk13/14 all saying different things on it so i think you should just do what works lol

one says use at the first sign of flowers, one says to use 1 week before harvest and another says to use at around 4-6 weeks in. sort it out canna!

Need to go looking more then at the Pk13/14 I was thinking the Bud XL was same as Boost not the Pk13/14.
Thanks Guy's, I know I need to do what the plants seem happy with, I wanted to get one basic grow done with so I get the feel of them and then look at better ways / mixes

3 weeks from the end normally week 5 of flowering.

As guy said above don't over do it.

U know when get it right as whole height level of your grow room drops with weight of the buds.

hey, just to say i dont think they are exact copies, just that the canna boost has no nutritional value appaerntly. So kinda can be used with anything or by itself, where as the bud xl is a humic acid and potassium , and nitrate supplement. I think..wait,
I just looked at there website seems its a bloom supplement,, where as the canna boost is more a pgr.(tricontanol).

take it easy all.
