if you gro in a good garden soil, supplement are not needed, cut fragments of dry wood or palm tree fibers from the tronc, or dry straw mixed up, mixed with soil for a 1/4 of the height of you pot.
Stop any type of nutrients. Before this year i have never used anything like nutrients, producing lots every year from my garden. I have used permaculture technics and philosophy to the garden, thats all.
all the best
