I have nitrites in my tank. I did a water change 3 1/2 hours ago. When should I do another water change?

There's no info here bluey.

Why is there NO2?

Is the tank cycling? How old is the tank?

What kind of tank is it? What's in the tank? What is your water source?

If the tank is cycling you should not be doing any WCs.
