La Huerta's Opinion

In sensitive plants, it is recommended to use Super PK starting from the 4th or 5th week of flowering.. 

For a swift commencement of flowering, it is recommended to use half of the usual dose during the early weeks of flowering.

Super-PK has a pH of 8.5 - 9 and can be used to increase the pH of irrigation water.
