The most demanded macronutrients by cannabis plants during the flowering period are Phosphorous (P) and Potassium (K). Despite these elements are already present in most nutrients for the bloom phase, adding a PK supplement directly absorbable by the plants can be useful for an explosive bloom (normally during the 4th-6th weeks of bloom).
Some PK boosters contain only these two minerals in pure form, like PK 13/14. Others - like Gren Sensation or Bloombastic - also contain vitamins, aminoacids, oligoelements or different plant extracts especially formulated to stimulate the bloom of plants.
These PK boosters do not replace base fertilizers since they contain neither Nitrogen (N) nor other necessary elements. PK boosters are used to increase yields, although they should be used with care since an excess of P or K can result in poor flowering.
