If you want the best pH pen for testing your nutrient solution, it has to be Bluelab.
Bluelab pH Pen
Adding nutrients into water will raise the electrical conductivity as the nutrients will contain metal compounds; and this is allows you to test the strength of the nutrients you have added with an appliance that reads the level of electrical conductivity throughout the solution and the best handheld appliance is of course the Bluelab EC Truncheon.
