right-now availability is important, so ash is the ticket... but it seriously alkaline, so use sparingly, (I forget dosage with it, google that...) and be bale to adjust the pH even for foliar spraying,.. I recommend humic-fulvic mixed in as well,...

Thank you sir I am going to give it a try.

Cheapest option is potassium sulfate (0-0-50) but not 100% organic, though it is a mined product and allowed under organic standards if a potassium deficiency is demonstrated on a soil test.

Another option is seaweed extract powder (0-0-16 0 which can be foliar sprayed or used as a soil drench. The potassium in this product comes from being stabilized using potassium hydroxide (also not organic) but allowed under National Organic Program (NOP) standards.

Or source a high K compost locally. This is most composts so it shouldn't be too hard, just ask for a soil test. Though this won't be as fast acting as the other options I mentioned above.
