I think I'm finding the same thing with my GE 9325K bulbs. Anything low down near the substrate like e. tenellus is starting to look a little ragged. Most bulbs will have an intense initial lumens rating and taper off to a lower level and maintain that for many years. Just need to add more bulbs.
I only connected two of the four outputs coming out of the WH5 ballast, so I'll just go and connect a third, and recover some of the lost initial lumens.
