APOLLOanswered grow question 4 years ago I notice you're growing in coco. and using canna nutrients. From what I know, the recommended ph level is 5.5 - 6.2 ... I know internet is full of places where they say 5.5 - 6.5 is acceptable, However, not all strains are hardy enough.
also I wud give pk after mid flower. They will fatten up with time. Good luck
