When it comes to topping it really does vary from plant to plant. As long as it’s healthy and growing well I’d say try the first topping and see how she responds. Cannabis isn’t shy about letting you know when it’s unhappy, so if you top it and she doesn’t start new growth in a couple days just wait until you start seeing her move again before you do any side shoot topping. Long story short, follow the plan you described just make sure to listen to what your plant is saying above all else!
