This has been my primary mix for years. I have added things and taken things away as new products have hit the market.
The best way to prove if something works or not is to take it away from the soil and see if plant shows signs of stress or negative change.
The only change as of lately is I substituted Sunshine #4 and mix it in at the rate of 50/50 for veg and then top off with 25% more Ocean Forest when I toss them in bloom.
If you want that earthy flavor Ocean Forest is where it is at. Only issue is it has poor drainage. I have found the more synthetic the nutrients used the higher the Ocean Forest ratio needs to be to maintain flavor.
