Just start dosing.
Here is how I did it when I needed to do extra water changes:
Add the right level of ferts to the new water on water change day. Does not matter if it is a 'macro' day or a 'micro' day, just add that days' ferts. You could also dose right after a water change.
Monitor the plant growth for a couple of weeks and see if you need to alter the basic plan.
