Growth stage sprays using the app

This is actually the hardest part of KNF to explain. This past year I went to 3 trainings specifically on this topic, and I finally get it. So, I have only done one lecture series explaining this in english that was recorded, but I have yet to process the video and put it online. Some of my older work attempted to explain nutrient cycle, but it has to be updated with my new and correct understanding to fully answer this question. Will updated this question with a new answer when I finally get around to creating the western mindset english material!
