Im running the canna coco line and at the minute i...

Nute wise it's better to err on the side of caution, use it weekly and, unless you see a P or K deficiency, don't add more.

Hello ! The PK 13/14 is a powerful nutrient so you should use it when canna tells you to , you can still introduce a low amount of it 1 or 2 weeks before the canna schedule and then slowly increase the amount until last day.The only time I used it was in hydro and I did like I told you and it worth the price. I hope it will help you 😁👍.

hey budda you don't really want to reduce your cal mag ever because you can t really have too much of the stuff and you can really start missing it down the line. Try using boost once a week along of the PK too much boost can cause P or K lockout and could hurt down the line so you want to dial in the boost as time goes on. I really like the canna but the bioboost let me down a bit the boost is quite weak in general but somehow still has too much P in it for some reason. Wait a couple weeks before you throw it in the mix. Good luck buffen these up nicely !
