Perhaps back off on the pk.
Cannazyme has pk in it as well.

I do equal parts of the cannazyme to a&b.

to me from what i have read it looks like a K deff.. leaves are curling up and rust colourd blotches are starting to form on the leave,

the younger leaves are the frist ones hit, and it seems to be moving down to the lower leaves..
