don't worry about that, changing in now a few days later will be more of a strain on stuff as you are putting them through the change twice. and 1375 to 1470 isn't really a big jump for Mg.. I have done 400ppm jumps with no adverse effects.

the dosing how are you doing it though and why are you doing a regular dosing routine for Mg? I just check mine after every water change and adjust at that point as I find it stays constant after it is fixed.
