Your plant is relying on every leaf it has to make the energy she needs to grow her biggest and best flowers.
Removing big fan leaves will reduce her capacity to make energy drastically, slowing growth and leading to potentially smaller growth.
People who defoliate and say "my plant grew fine, look at the big buds" are kidding themselves - had they left the leaves on, their plant would have grown even more and had even bigger buds!
The "shaded potential bud sites" are actually relying on those big leaves to make the energy for them to grow their best, making removal counter productive.
Besides, in 2-4 days those "potential bud sites" (branches) will have grown out from beneath those leaves anyhow!
Cannabis has evolved over millions of years to grow her biggest and best flowers.
Getting rid of perfectly healthy, green, energy producing leaves for no reason or benefit, is not part of that process.
In over 35 years of growing, I have never seen a plant that sheds healthy green leaves at any time, ever!
