These products are designed to suck new growers in...then people are like, "hey, look at my awesome buds, these products work" but that's only because they don't realize they can grow the EXACT same buds with a regular 1, 2, or 3 part formula. There are some things that add to a grow, but which are totally unnecessary. I like fulvic acid a lot, but it isn't improving my buds-from what I can tell, I just use less nutrients with it for the same result. Instead of those products, people should try out the bio-fungicides for PM and botrytis prevention because at some point you are likely to see one or the other. OR try out one or two things that "stimulate acquired resistance" like aspirin water (cheap!) or chitosan.
