use of pk 13 15

hey riu. starting my fifth wk of bloom and was won deriing what u guys think of canna pk 13 14? the bottle says use for a single week three too four weeks before chopping though ive heard of other ppl using it quite differently. also has any one done a side by side test of this product, what where your findings?

Stick with the flores, pk is stronger has no N and your only taking risks. Flores alone will give you the weight and no PH correction needed.

sorry mate, flores? u aussie too im guessing from ya pick??
