Canna nutrients

I don’t run the Canna line, I use Advanced Nutrients, but PK use is the same for all the nutrients imo. I start using the PK when flowers start appearing on the plant, real flowers and not just the odd pistil. I use it at 1/4 the rate recommended on the container until mid flower then I increase it slightly to about 1/3 to 1/2 the recommended rate for a couple of weeks to get them past the high demand during flowering. I keep the PK in the feed during flower to help the buds fatten. The last 2 weeks are water only for me to let the plant use up what she has stored and reduce the chlorophyll some too.

Be careful with the manufacturer recommended feed levels as they are almost always too high. The company wants you to use more so you will buy more but their recommended rates are a bit too high for me. I used the recommended rate on my first grow and the weed was too green and harsh that run.

Solid information there now. You can take that to the bank. 👍  

Yep I'm going to agree with monkey here, I run canna a+b as my base and then green planet for everything else including pk, I will start adding it at 1/4 strength when they are showing actual bud development and then run it right through till about the last 3 weeks, I then pull just the pk booster but keep the massive bloom and liquid weight etc still running. That way I'm still giving them enough pk via the massive bloom but not overdosing them with the pk 14/15, I will also only ever feed the pk14/15 at half dose max and I work up to that over a few weeks. They really don't need the full strength and you will more than likely run into more issues with lockouts if you follow their full strength schedules. Hope that helps

@bubblehok when you use green planets pk spike, do you put it in every time you water, or just once a week till 2 weeks before Finnish?

@pirate33 every water bro

To clarify i use it from the start of flower through till about the last 2 weeks. In the daily feed, usually if Im doing autos(which is most of my indoors) it's from about week 5 through to week 8 or 9 then last few weeks I cut the spike.  

Thanks for the info i have been using it once a week.

I’ve been using all of green planet range, they seem to be pretty good.

thanks

@pirate33 yep i use the full flower range myself, liquid weight, massive bloom, pk spike and rezin. It is a fantastic nutrient line. The rezin is the bees knees imo, I cant get over the terp production and they frost up so nicely. 

@bubblehok I use them at half strength every second day, 7 litres to each pot with about 1 litre run off
