Best Potassium Source for Foliar Application


Well-Known Member
Hey guys, one plant of mine is currently showing potassium deficiency. I am foliar spraying her nearly every day with Neem, Nirvana, Aloe and Seaweed.
What could i add to the mix to feed her some potassium?
I have a bottle of diluted potassium silicate which provides around 4% potassium.
Could i use a mineral bottled nutrient like Flora Grow, which contains 6% of KO2?
Will the stomatas assimilate it? I adjust the ph between 5.8 and 6.5
