Vitalink PK is a highly concentrated potassium and phosphorus boosting additive for targeted use in the peak week of the flowering cycle. This week is when we wish to increase the potassium and phosphorus to nitrogen ratio to it's highest level, therefore we recommend substituting Vitalink Buddy with this elevated level of PK for that extra push.
Vitalink PK will increase the size, density and overall quality of flowering mass and is applicable at 1ml per litre.
