Canna PK13/14

depends on the concentrations of p and k you end up feeding it. if you do use it, it'd be wise to adjust your other nutrients to achieve a safe concentration and ratio of whatever you are feeding to the plant. if you want p/k to be boosted for a specific period of bloom, do so in a planned way. above the knowledge i can pull off the top of my head, but if you play with these things, you better learn it. molarity is a wiser thing to compare, anyway. ppm could be by volume and if so is useless in anything but a rudimentary/imprecise function.

Hi there! You should use pk 13/14 in the last weeks of flowering! I was using it a bit earlier as the plants looked like there is more potential if I use it. But when given more than 2–3 weeks before harvest I would recommend 1/2 of the Dose!

Hey buddy :-) I use Canna Pk 13/14 ca in the 5 - 6 flowering week when the flowers start to swell :-)

Hello.. Hope you are well.. They lookin great.. Big fan if the sp range lights aswell..👍.. Pk is very, very strong.. If my plants are huge and really looking healthy still on last wks of flowering i still wudnt go full dose tbh.. I usually hit the 10ml mark but slowly introduce it to her over period of wk then get her 2 the mark on 2nd wk.. I will then flush and harvest so its literally the last boost u wanna give her.. Try dif dosings cuz all plants will react dif n ive never grew D poison but b very careful still.. Less is best in my personal experience with it.. Stay safe n gud luck.. 👍🍀
