The macro-nutrients will definitely be insufficient. Though some micronutrients are present, but it is better to top-up.

Each of our tanks is different. In these links are some suggested values and are very good for a start. You may modify your dosing later based on your plants requirements and water-change regime etc.

Do consider Lushgro Aqua. It almost has everything inside except PO4 and Ca. Every 25ml into a 50L tank gives you 15ppm of NO3, 25ppm of K, 1.4ppm of Mg and 0.1ppm of Fe. On top of Aqua, you may need to add a few grains of KH2PO4. Your Ca from Equilibrium or Coral or regular weekly 50% water change (your choice). That dosage is sufficient for about a week. If you have a 100L tank just double the dosage accordingly.
