Best fertilizer organic for house plants?

Question by MICHAEL R: Best fertilizer organic for house plants?
I have been using organic fertilizer for months now and nothing seems to be greening up my leaves. I have gardenias, citrus trees and jasmine and the flowers are ubundant though. I have been all kinds of fish fertilizers and especially Neptunes Harvest and yet leaves are still light green to yellow. I have been told Organic is too low in nutrient for plants needs..What is the strongest Organic that fills all the house plants requirements for deep green leaves and flowers? I am tired of supplementing stuff like Epsom salt and others to hopefully think That it will help the organic not working for me.

What do you think? Answer below!
