I am using Canna nutrients in soil. my ph has been at 5.8-6.1 and my EC started a 1 and has slowly risen to 2.1. when i used my PK 13/14 the EC went up to 3.8.

I stopped using Rhyzotonic & Cannazym and the EC dropped to 3.3

I ended up just really diluting the feed, instead of making 10l i made 15l with the same amount of nutrients just to get the EC to 2.5.

Does anybody have any expierience with Canna PK13/14.

I am ysing Canna Terra Flores & Canna Boost alongside the PK just for one week.


​please help!

ive used the canna coco line for a long time, its obviously the same additives, ive never had and thing like that happen to me, i measure in ppm, but again ive never had it spike so drastically, you are applying it at the recommended dose right, i think its 6ml/gal...

i use a pk booster in week 5 of flower. when using canna, or any others, always reduce your base nutes. if you don't, you'll burn your plants.

I used it in week 4 for 4 days on a 7 week flower cycle. The plants did burn a bit but are still looking good. SDC12036.jpg I am using it again on another crop again week 4 of flower but on an 8 week cycle, this time i have cut my base nutrients (Canna Terra Flores) and am using half the recommended dose of PK 13/14 (10ml per 10l) but still double the recomended dose of Canna Boost (40ml per 10l). for some reason the Canna boost didnt seem to up the EC or PPM.

Thanks for your help folks.

If your following the Makers feeding charts. Worrying about EC or PPM is not a problem. Are the leaves (starting with the lower fans and going up) yellowing? No? Then with a P&K booster in use, you have no problem.

You are using it at the right time, so don't sweat it and run away!

Are those amounts freshly picked or dried weights? I only ask because I have been using your EC guide for the last 8 weeks and so far the results are much better than the 1/3 canna recommendations, much bigger and healthier plants.
Also wanted to take the opportunity to say thank you.
One thing I'd like to clarify though, and that is are the EC's total EC's or do I add pk 13/14, cannazyme etc. after reaching those EC's given in your guide? So far I have taken them to be total EC's.
