Hello everyone I was just checking out the canna website having a read up on PK 13/14 and I found something interesting as never noticed before...from the canna site they recommend using PK 13/14 alongside the canna boost only for your weeks feed not using nothing else but them too, am I reading this properly lol as I normally introduce at week 4 at half strengths then full for the 5th week including all the other additives an Nutes...This is where I noticed it any idea's? Thanks Spiderman

I read at as three separate regimes:
1: Start with water, add 1-2 ml/litre of 13/14, and then add normal nutrients to reach the correct EC.
2: Proceed as above, and then add 2-4 ml/l of Boost.
3: Start with water, and add 13/14 only until you reach the desired EC.
It looks like you should choose only one of these, not all of them, per crop.

It sounds like they are saying instead of adding A& B you just use more Cannaboost.. which is a shiteload more epxensive than your A&B
To be honest even their suggested 4ml per litre with A&B is a con

Most folks have have tailored to their own requirement, this is how i do it on a 10 weeker in coco....
Veg period Coco A&B + 2ml per liter Rhizo Ec @ 1.2
Flowering as soon as switching to 12/12.....Coco A&B + 2ml per liter Rhizo Ec @ 1.4
One week after switching 12/12.....whether buds forming or not 2ml per liter boost. Coco A&B Ec @ 1.4
Two weeks after switching 12/12.....3ml per liter boost. Coco A&B Ec @ 1.6
Carry on till week five
Five weeks after switching 12/12.....1ml per liter PK. 2ml per liter boost. Coco A&B Ec @ 1.6
Six weeks after switching 12/12.....2ml per liter PK. 2ml per liter boost. Coco A&B Ec @ 1.6
Seven weeks after switching 12/12.....3ml per liter PK 2ml per liter boost. Coco A&B Ec @ 1.6
Eight weeks after switching 12/12 flush

I do the exact same feeds as you really mate just a lower EC... I just don't get why u would use just boost and add PK to your required EC without anything else for a week ... Just seeing if anyone has tried this because I would give it ago if not ill do as I normally do like above

I was told this year to get the highest THC/CBD to feed No N. last mouth of feeding. Don't know if it's true or not but I can see why it could work.

I think it would be wrong to hold back on the micro elements contained in the A/B at such a critical stage in the plants development.
I know the plans will have some of the elements stored, but will there be enough for the plants requirements ?
I'll stick to what i'm doing as its always served me well.

Yeah I see what your saying mate, though when you get to an Ec of 1.6 with 3ml per liter of PK and 2ml per liter boost with a background Ec of 0.4 there is only a piss full of A/B in the mix. maybe thats why it works, cause you're replacing one with the other while retaining the micro elements.

But if just using pk boost say to reach a desired EC of 1.6, it`s gonna take fuck knows how many mls per litre, but it`s gonna be 10+ ml per litre at a guess and more, maybe.

I like feeding N. TBH but this year I feed very little and my plants are the best I ever grew but might be the new Nuts or I am getting better lol all I know is I am already looking forward to next year. :)

I was reading summink the other day about PK boosts, thought i`d bookmarked it, anyhow it said it`s not actually the added P & K that boosts the plants buds, but the reduction in N, forgot exactly what it said i was hammered again and cant find it now.

I aint seeing this Jimbo The Canna PK Bangs my Ec right up at 3ml per liter.
600 ml of Pk in my 200 liter rez @ 3ml per liter, cant remember the exact figures in regards to Ec but i'm sure was around 1.2 which only needed 1 to 2 ml of A&B per liter to bring it up to the 1.6 anyways gonna be at this stage in a couple of weeks on my crimbo run, so will defo take some readings.

Ok cool m8, i`m not sure how much, but i always seem to use lots of canna PK boost and it just never seems to move the EC like NPK does, fuck knows TBH.

Another thing mate ive just noticed, they have changed the label on the bottle and i've never seen them directions before
Where did the directions in the image come from, Canna ? maybe they have changed the formula.
Canna site seems to be down at the moment.
