Hi.
It all depends on your available budget. But from my personal experience with Gex, normal garden soil, JBL base fert with Lapis and ADA,
I think I can safely and confidently conclude that ADA is one of the best. I have personally witness and observe with my own eyes how the ADA substrate system revive dying and yellowish hair grass.
So as much as I want to recommend to you the ADA system, a lot depends on your available budget actually.
