Well it looks like you’ll yield about a joint with that plant if you’re lucky.. As far as nutrients.. If you’re running “organic” and trying to force the plant to your will you should reconsider organic, because you’re not benefitting at all from it and are only slowing yourself down. I’m not sure what you’re trying to accomplish and we also really can’t help very much with such limited information.
Potassium is important throughout the entire grow. It’s responsible for transpiration. This plant needs 17 elements and not one of them is any more important than the other. You could have the maximum amounts of all the elements but if you’re short on 1 that’s the only thing your plant cares about.
Now that I’ve chapped you a little bit I’ll answer your actual question. When in flower your plant wants increased amounts of P, and K, and less nitrogen to a certain point then none as you round the final corner to harvest. There’s multiple places you can cut corners and speed your grow up, but using organic nutrients kind of hinders you speed wise automatically unless you’re using organic acids as well.
Going forward, I would suggest looking into ways to speed your grow up that don’t involve starving your plant of light. Such as organic acids (fulvic, Humic, etc.), improved aeration for more water, CO2 to allow for increased everything. There’s more but I don’t want to hold your hand for you, you won’t learn just by following directions.
