plant is droopy

im about 3 weeks into flowering and noticed that my top branches fan leaves are drooping towards the ground.
i went through the pics in the sticky to try to find my similar situation and nitrogen toxiticy was the only plant that looked similar.

I did cut off alot of fan leaves a week prior to this, i was trying to get light to lower branches with my cfl lighting. i was using 20-20-20 throughout vegging, and switched to 10-52-10 for budding. take a look at these pics and any advice is greatly appreciated.
