I ran Fox Farms Happy Frog for one grow. Great soil except it ran out of everything at once in week 4? of flower. At that point the grow became de facto soilless ... I fed with complete GH nute and got a good result.
Happy Frog is weak and works best for seedlings. FFOF has more nutes, but usually burns seedlings until they get used to it.
Unamended FFOF is good for about three weeks. If you want a water-only mix, you've gotta spike with compost (or worm castings), plus a dry fert like Epsoma or Eco scraps.
Personally, I like weak organic soil that can be easily supplemented with nutrient tea.
Organic soil that is too hot is very difficult to adjust.
