it's going to hurt it a lil bit for like a day, then it's going to love you.
by flush i mean watering with plain water at 2-3x volume of the pot when you would normally water. this helps elmiinate salts that build up during the course of fertilizing.
The reason I mentioned it is that when you start to see the ridges of your leaves starting to raise, this is a good indicator of salt build-up and it may be time to flush.
In general, flushing every two to three weeks is very good, once between veg and flowering at bare minimum.
the main point of flushing is to recondition the soil, so repotting would defeat the purpose. Just make sure you have good drainage - with a good amount of perlite, for example - and allow the soil to dry as you would after you water. You should be watering enough when you regularly water so that water drains out the bottom of the pot, so flushing doesn't really saturate the soil much further.
Each volume of water you run through the pot can dissolve a set amount of those salts as it runs through. By running more water through, you're dissolving more salts.
