I always cut my fan leaves away to expose bud sites all the way through veg and flowering and my buds are fat and strong and never hermie.
In the final week or 2 theres not much leaf on my buds at all.
Id hate to think how much crappy leaf people grow for no apparent reason just because they read it in a book when they want to grow buds not leafs.
Plants in a cupboard or grow room don't need excess leaf as they have no predators and no need to store as we feed them.
Buds grow their own little leaves anyway.
Grow buds not leafs.
This is all my opinion.
Its what i always do.
Here are my pics.
I don't want to argue about it just do it how you want to
