| Well, it doesn't look like a bacterial problem to me. Bacterial infections have a clear or watery character. Yours may be from some kind of bug, fungus, OR, cold water on the leaves. Watch out for cold water. I had some damage from cold water, then moved my RO water tank beside the GH, opened the wall, and insulated the tank/GH area. Then recently added the largest aquarium heater they make. Works great. After that, the only damage I saw on my Phal leaves I have attributed to neem oil use.
