You should check out Hoocho on YouTube, he is a wealth of knowledge for hydroponics.
I top up my nutrient, usually every week and since the plants are bigger I rub them at it closer to 2400. Now that also depends on the plant. It is good to change the water periodically but I don't personally. Get a EC or PPM tester and maybe a PH tester (although my water is good and I never test the PH).
Led lights would really help on a timer. And to answer one of your other questions I have the water on for 20 minutes and of for 10.
