canna coco a+b during flowering

  1. I'm finding that i need to cut the dose back mid flower or she starts to develop some tip burn. I've got Nirvana's Ak48 growing at the moment 3 weeks into flower with a little nute burn starting on the tips of the leaves. Here is my setup

    600watt HPS in 4x4 closet
    Canna Coco a+b 3.5ml / gal
    rhizo 2ml
    zyme 5ml
    GH koolbloom 3.5ml
    calmag 2ml

    ppm 655, this seems like low end of nute levels but every grow every grow has started to show some burn at this point, any pointers??
