Given the growing conditions you describe, I'd say at least 17 times a month.

:)

how about "when it needs it?"

LOL Ok, but is it a heavy nitrogen feeder? I have slow release pellets of goat/sheep poo and my own pee.

And compost but the pot got kinda overflowing by the compost already....need time for the topsoil to settle down.

well, they need more nitrogen than tomatoes, but lots less than cucumbers. it has been my experience that they'll want a little bit of N here and there, but are more prone to wanting P and Mg.

Other than compost what organic stuff can give more P and mg?

Bone meal is a great source of P. Epsom salts for MG.
