I recommend measuring flour in grams, but if you are measuring using cups, be sure to spoon-measure: use a spoon to add flour to the cup, then use the back of a knife to level the top, without packing the flour in.
If you're using frozen blueberries, juice may discolor the batter. To minimize that, place them in a sieve or colander and run water over them until the water runs clear. Then pat them dry and fold them into the batter as carefully as possible.
