I used canna pk 13/14 around week 4 of flowering thats what the guy at the hydro shop said to do. I'm finding now that most people say to do it around week six (my plants are suppose to be ready week 9). Would it do any harm to put my plants through a second round of pk 13/14?
you use pk 13/14 3wks before harvest dont matter wot type it is or how many wks if it was 7wks o flowering you,d add on wk 4 if it were 9wks you,d add it at wk6 you get me you could add a little on your proper wk but use half strenth or less ok bud
hi bb you always use pk 13/14 @ half strength,when it`s applied once in the plants life cycle,as you say the 3rd last week of bloom peace out bud
