I do not have access to tobacco stems. What would be a good source of potassium for WP?

Any nightshade family of plants can be used.

Drake's library names comfrey for potassium and phosphorus, in a discussion of fermented plant juice. (Office Hours Ep. 15, 54:03)
A KNF text also lists potassium from the tips of healthy leaves, as fermented fruit juice, among its bio-organic fertilizers. (Unravelling the Mysteries of KNF, p. 60)
Tobacco stems are the WP source in the recipes because most of the potassium is in the stems. (Office Hours Ep. 17, 34:33) The method is simple:
- Grind the stems coarsely, bag 1-2 kilos, and soak in 100 liters of water. (Office Hours Jul 2025, 1:06:32)
- Dilute 0.7 L of the crude liquid with 20 L of water to use it. (Cho, Recipe, p. 73)
The library gives no WP recipe for comfrey or any plant but tobacco. Comfrey and leaf tips appear there as fermented juices, not WP. It also does not mention the plants named in the earlier answer.
