Probably too late now, but definitely suggest new bulbs if 9 months old, and when reducing the lighting period, I'd recommend reducing it slowly, i.e. an hour a week, rather than just drop 4 hours in one hit.
Not sure how you reduced yours, was really answering for information
. Equaly increasing lighting should be aproached the same way.
