I had the same problem 2 years ago.

all the fan leafs fell off early on. but much to my suprize it keeped on budding anyway.

here R some pix to show what I mean.
first few pic is befor the fan leafs fell off.
last pic is after the fan leafs fell off and she was about to be harvested.
in the last pic I was about to harvest. so I had taken about 8 other CLF lights out of the closet so I could get a better pic.

well best of luck to U.
