I haven’t had disfigured leaves, but I had noticed some of the plants closest to the light (a set of anthuriums) had this curious yellowing occurring to their leaves that I thought was related to being pot bound. I now think the high intensity was slowly damaging the leaf cells. Thank you all for your input. I decreased the intensity for many of plants and reduced the ‘day length’ to 12hr 30min from 14hr. I’ve already seen improvement from my phals and paph. They got the most dramatic adjustment. This will also save me on my energy bill.
I’m just slightly worried I might confuse the catasetinae with this sudden decrease in day length.
