Hey again... Definitely lots of phosphorous for flowering, that promotes budding and large ones at that.
The list of different fertilizers is virtually endless. A good choice is the Foxfarm line of nutes. They aren't totally organic, but I have used the line in my hydro grows as well as in one soil grow. Try to focus on what you use for dry ferts. These will have a huge impact on your soil and soil is what is in contact with your roots at all times. It's like the shoes on your feet. GL finding the perfect fertilizer for your growing style.
