What is your nutrient mix for vegging and flowering and how often to you fertalize your plants. Do you use foliar sprays as well and how often. I need to know this bad, I've been givin them way to much or way to little nutrients.
If you use chemical ferts, feed once every two weeks. I give mine 20-9-9 for veg and 9-20-9 for flower (or something like that). I don't like to foliar spray because the lights (especially HPS) can then burn the leaves when wet and can increase the chances of getting mold.
Not sure about your question because I have not grown organic yet but, I think you can just mix it in with the soil initially and that should cover it for a while. Maybe some of the organic pros will respond. Anyone?
