I don't know what potassium does exactly. But when you don't have enough of it your plant your plant gets potassium deficiency and your leaves start drying and plant becomes weak. There is no fertilizer designed specifically for THC production. But read some of the guides on this forum, they make some suggestions on what's best to use.
