The only things I can think of here are:
1. Too much nitrogen. One of the things I hate about Advanced Nutrients is that you can NEVER find the NPK of their products... but if they're anything like others, that Micro has a lot of nitrogen in it... Nitrogen is needed in veg state but flowering, while it needs SOME nitrogen, doesn't need a lot...
2. You're over-watering? You don't tell us the size of your pot so I can't make any kind of judgement about whether they're getting too much water or not... if you lift the pot every time you think she needs something and its super lightweight, then you're ok... but if you're watering when there is still some good weight to the pot, you're overdoing it and are risking the next thought:
3. Root rot.
Good luck...
