All right, I've been trying organics with the round of soil-grow girls I've got going right now, but I've been giving them bat guano for nitrogen, bone meal for a little phosphorous (Not flowering yet), and putting that in a mix of peat moss and organic soil. So I'm realizing I've got to be real low on potassium in my soil mix, but I don't know if it's slowing the plants down or anything. They look great, but I know for a fact that they have almost no potassium! So how well can they really do with no potassium, and where would I find some sort of organic potassium supplement??

ash from hard woods, like white oak or elm

You don't need a lot, in fact too much may knock the potency down - in a study I read...

Green sand is probably the best organic K supplement, but it's best to add it to the soil when you mix it.

Earth juice catalyst has plenty of K and lots of other good stuff

i coat the top layer about 1/8th to 1/4 inch thick then mix it in so its dispersed nice and evenly.

You can also use Epsom Salts for potassium. You can add some into your soil before you pot, or top dress with it. I guess you could dissolve some in water as well, but I've never tried that.

You don't need much, probably just a table spoon per gallon if you're going to top dress. I'd start with a teaspoon per gallon if you want to add it to a tea or something.

I believe the epsom salts are faster acting than greensand, because they are water soluable.

epsom salt is magnesium sulfate MgSO4.7H2O and does not contain potassium so i do not know why epsom salt would help low potassium maybe you are thinking of the table salt alternative potassium chloride?

composted banana peels will work for you bro

I'm not sure man. My bag says 0-0-22 on the front.
