Is it laying down due to the weight of the buds? looks like you may have some deficiency's caused by nutrient lock out. I have been going through the same thing with one of my plants so I know the look well . Mine isn't laying down like that but the fan leaves look the same. My problem was from too much nutrient build up in my coco at the root level. A good flushing got it back on track for the most part. If I could offer any advice it would be to switch the type of pot you are using. Try an air pot or some cloth pots or something along that line they really help a lot!
