There is no real purpose in cutting back light, duration or intensity in the heaviest building period of normal flowering plants.
There is a point to doing that with long flowering narrow leaf. They may never ripen otherwise.
As always it's growers choice. It will speed up ripening but cut back on weight and density during a vital period. Narrow leaf long flowering already built up so much, can't figure it hurts much.
