Hey Guys sorry I haven't posted in a while, but I'm back!!
My Den's, Epicats and Nodosa's are doing the same thing. Was a bit concerned at first, until the Nodosa bloomed. I then figured that if they bloomed and continued to look healthy despite the shading, I didn't have much to worry about. I would say to just continue on it's regular feeding and watering schedule, and it should do well for you.
