Not always, depends upon the plants to some extent. Aquatic plants take in nutrients through their roots, but some also through the leaves (various species do this more or less than others). Some are heavy root feeders, like swords and crypts; these plants are, as I mentioned in a previous post, mostly bog plants so they have good root systems and benefit from root fertilizers like tabs, sticks or substrate additives. But plants that float, stem plants, and non-substrate rooted plants like Anubias, Java Fern and Java Moss gain little (and more probably no) benefit from substrate nutrients.
I have always had superb plant growth using weekly liquid fertilization and substrate tabs/sticks next to the larger swords. Swords are particularly heavy feeders and while mine grew fine with just liquid, the addition of Nutrafin's Plant-Gro sticks resulted in phenominal growth after 2-3 months and it has continued. When I added the root sticks, I reduced the liquid fertilization from twice to once a week; I've now gone back to twice because some of the non-rooted plants clearly showed signs of nutrient deficiency, and they have now recovered.
So my recommendation would be a complete liquid like Seachem's Flourish Comprehensive or Kent Freshwater Supplement, and a tab or stick next to each sword.
