strange this problem during growth, however, as you well said, it seems too much of N to me, for this reason I say strange in growth.
seeing the doses you give (very low right) the only problem that comes to mind is the frequency, you give nutrients and then water 3 times? you may be building up nutrients in the soil if you do otherwise despite the small amount you inject.
Don’t worry and get a good routine for nutrient and give her less N ( she is like if need only a little of it) also diring flowering 😊✌️🏽
