I avoid corners. If you allow the plant to do the heavy lifting and make its own decisions, then it leaves us only with the task of ensuring they get water. If my plant thinks it needs to summon more bacteria via sugary exudates that include protein molecules that signal genetic changes in bacteria via quorum sensing in order to supply extra potash at exactly 2pm on the 15th day after flip, I don't argue with it. Frankly I don't care either. My plants can do whatever they want if it makes them happy.
Adding sugar to brewed compost teas is one thing, but adding it to the soil with growing plants is a questionable practice IMO. At the homeopathic level that most use in their watering, it probably makes no difference. More sugar though on a regular basis could have negative consequences, since sugar has zero nitrogen and is basically soluble carbon and easily digestible by bacteria. An application will definitely lead to a temporary explosion in bacterial growth and an fast reduction in available nitrogen. That's not usually what we want. Plus I wonder what sugar does in soil and how it may affect exudate signaling.
I tend to keep it very simple. It helps me avoid corners. Otherwise I'd be cutting those corners with a chainsaw. I have other hobbies and past times that use up a great deal of my time, so I like to keep this hobby worry-free and not have it take up more than an hour a week or so at most. (Until trimming time of course
) lol
