Canna Terra Product HELP

Hi all, has any1 used the canna terra range of nutrients/ additives? Iv been using terra veg for growth/ vegetation stage and its been fantastic. right now shes starting to form flowers/ bud sites so iv gone and purchased nutrients for the flowering stage. Heres my questions to you, when changing to terra flores for blooming/ flowering, would you use terra flores/ cannazyme/ pk 1314 all in the same mix?. Would 1 counter act against the other 1? The canna website is helpful but not for this it seems, unless iv missed something. Thanks in advance tokers

Im planning on starting a grow using CANNA soon. this really gives a good understanding of what you need. and by the looks of things its recommended not to add pk13/14 til bout the 4th week of flowering. and only for that week, but theres alot more info on the official thread https://www.rollitup.org/general-marijuana-growing/225396-official-canna-coco-nutrients-thread.html
