Welcome to the forum. You'll want to read more than the substrate sticky. Search around through various tank journals and really get a feel for what you like and what people say both positively and negatively.
That said - you'll likely be using root tabs with Flourite. How many tabs and how often will depend upon the plants you've got and how quickly they eat things up.
If you'll be high-tech with high lighting and pressurized CO2, you'll be dosing dry or liquid ferts into your tank on a daily basis.
