i use fox farm ocean forest (ffof) and all organic so i feed every watering. if your using chemicals or high nutrient organic ferts I would recommending watering then feeding then watering and so on. if its high nutrient chemical ferts i would recommend feeding 1-2 times per week. 2 at the most. you honestly just need to learn how to read your plants, all genetics are different, some want a lot some want very little.
