The Fundamental pack are micro nutrient. You should really get the Enhancer Kit first. Both would be better. The Enhancer Kit is all the macro nutrient which your plant use the most. Without those, the plants will have a hard time taking in the micros. Dosing all the micro nutrient without the macros with low light and no CO2 will cause problem in the long run.
Easy plant with easy fix. But its up to you...
