Flourish root tabs is a comprehensive fertilizer that cover most of your nutrient needs but is isolated to the substrate, great for heavy root feeders like the amazon sword but not so great for the java fern which shouldn't be planted in the traditional sense.
The java fern and cabomba would benefit from Leaf Zone, but they may also need other supplements like nitrogen, phosphate, and more micro nutrients. It will depend on your light level and rate of plant growth. The more light you have the faster they grow, and the more nutrients they'll need.
