Potassium Problem

Last week I had a rodent problem, with a mouse that ate at the bottom of a number of my plants...... the original thread was here https://www.rollitup.org/marijuana-plant-problems/286405-please-check-out-its-new.html .......... During this same time temps have dropped here significantly and I have realized slh isn't a big fan of 50 degree temps. I have dealt with that, but the plants that have been chewed on are now showing bad signs of potassium deficiency. I am assuming that the damage to the stalk has disrupted its nutrient uptake and I can cleary see how this specific damage might cause K problems more so than others. Im not quite sure what to do, possibly some foliar feeding even though Im closing in on my halfway through flower mark, Im not totally against it.
