My plants have not been growing in well. The first four are getting gray patches on the leaves, isn’t that from a type of fungus? The epiphyte didn’t have any marks on it until this week. The Episcia is looking even worse than when I received it, it’s gotten a lot more limp. The Fittonia is also struggling, at first it started to perk up but now it always looks limp and the leaves are curled. Not pictured, my Selaginella uncinata looks bleached, and I think that’s because I sanitized my plants for too long. However, I moved it to a shaded part of my tank so that it can sprout some new growth elsewhere. Should I trim off all the dry bleached material?
