Pk 13/14

[Riff Raff]

Right a quick question about using pk 13/14.

Do i mix it in with my normal grow & bloom feed or is it given seperately.

From what i can gather you only use it the once. Is this right?

How much do i use? is it half the strength than what it says on the bottle?

I know there's a thread about it somwhere but i'm fucked if i can find it.
I'm not being a lazy bastard, just can't locate it.

Damn short term memory loss.

I always give the pk at week 3 to week 4 of flowering at a rate of 0.5ml per ltr and slowly work it up to 1ml per ltr by the end of the week of using it. You only use it for one week (about 2 or 3 feeds). You just add the pk to your feed mix.

just to add a little controversy. I use it (half strength at first, building up to three quarters strength) from week 5 up to week 7/8 depending on how long they have left to flower..

This confuses me a bit mate.

I often read about people saying use something for one week / a few feeds.

The thing is I use 8l pots and I only have to water them every 4-5 days so thats only like 1.5 waters per week.

So how do some people (like you have said LK) say 1 week / 2 or 3 feeds?? There is no way I could get 3 waters in, in one week.

It really depends on alot of things why some people use more or less water/feed in a week. I.e bigger plant's use more, small pot's you would use more, high temps you would use more. So there is alot of factors that change from peoples grow rooms that cause for different needs.

In your case i would give the pk at 3 watering's/feeding's however long they take to do.

What time you choose to give the pk to them is upto you, as you can see i use one time and asci uses another time frame and someone else i know uses it at week 7 to 8.

That's how i use it too M8 ... 3 feeds over 7-10 days starting at @ week 5.

Do you just add this to your usual nutrient mix or on its own? Ill be using this a few weeks so..

just add it to your usual feed mate...

lovely cheers.

This is the first time I'll be using it as well, think i'll start at week 4 and then 3 feeds at 0.5/0.75/1 ml/l, i water every 3-4 days so i guess my treatment will take 1 1/2 - 2 weeks
Using biobizz which will mean I'm giving 1ml grow/3ml bloom. Not going to be doing in at week 3 as they are due for a burst of epson salts
Hope i don't burn my plants lol

When you use it, depends on how long your strain flowers for.
PK is supposed to be used 3-4wks before harvest.
So in a 8wk strain that is wk3 or 4. And a 10wk strain would be wk5 or 6.
i have tried both ways - feeding for one week and feeding for several weeks and it is strain dependent but my results show that it worked best run for 2 weeks.
First week at half strength and 2nd week at near full strength.

I have also run it combined with the other nutes and on it's own.
I did notice a big difference when run by itself at you tanks normal EC level but you have to watch for burn much more carefully.

good luck,

That makes sense to me. When I read the instructions on the bottle, and saw the 3 week thing I immediately thought of the final swell at around that time of the grow. I shall be using it at around that time, mixed with Bio- Flores and Boost to give an e.c of no more than 1.0

[green_machine]

I just re-read my post and thought that I should clarify something.

When the PK is added into the mix with everything else...like nutes, additives etc, you have to add the PK and additives first - then add the bloom nutes to your desired EC level.

Sometimes adding it after everything else raises the EC more than you wanted and the only way out of it is to remix or water it down. Watering it down will then dilute everything else that you mixed accurately throwing the whole thing out the window into close-enough land...

Plus I take back what I said about using it by itself...the results were great big buds but shabby plants.

You can also try using Potash (essentially PK) all the way through flower in a cresendo until you reach the time you want to dose with PK. Helps get the plant used to the increased availability of the Phos and Potassium and glides the PK needle in effortlessly.
My heaviest harvests have been acheived with this method.

rite lads, well asci, LK and diaps, in particular

well were gonna use the PK for the malonica, now they have 6 weeks to go roughly, at the moment there on grow and bloom, my question is when should we add this for the malonica?? and how long should we use it for? there at day 54 atm guys

thanks for any advice in advance folks

I always use PK at week 3 or 4 for 7 days and i always lower the bloom by 1/2ml whilst using the PK. So i wouldn't like to say that far into flower mate. I know others do use it around that time and im sure they will be able to help you.

[Diaper]

I won't be using it unless I start using chemical based nutes, which means hydro!

cheers LK i know its normally week 4, but i was thinking it may be later with the mals as theyre a 90 day finisher roughly

so you wouldnt reccomend it with bio nutes diaps?

[Diaper]

In a word, no.

As has been mentioned in your infimary thread, PK is a chem based nute which will not be beneficial to the micro herd. Or in other words, it'll mess with your the organisms in your soil.
I haven't used it, but it all makes sense to me. I had my suspisions when I ordered mine, see I thought the lads were all running Bio-Canna not the chem based Canna Terra range.
It's a personal thing, I want to grow organic bud so adding chem nutes is a no-no. That's also the reason I don't use compost with John Innes, but that's not to say it doesn't work!

Now, if I were to run a hydro system things would be very different. Unless of course I went down the organic hydro path, but I doubt that'll be happening any time soon.

[asci]

I find it works really well with the terra range. Start around week 3/4 of flower then continue up to week 7.

ok lads thanks alot
