Any idea what can be wrong with my Glosorium. I have it in a south facing window with a sheer shade for indirect light. It’s also by a humidifier. I was going to add some coffee grinds for acidity but figured I’d come here first.
With the yellow halo it's usually fungal. And with the edges yellowing, overwatering probably contributing to that. If this is just a single leaf node, you can downsize the container to help with that too. It's just a bit of a pain stabilizing the larger leaf
0 gillningar Thank you I’ll send you a better picture. There’s a few leaves. It was a cutting given to me about 2 weeks ago and it looked great then!
0 gillningar Oohh gotcha!

So maybe just a repot into something smaller ?
0 gillningar Yeaaa, that's freakin tough, cuz that has gotta be top heavy. Usually i try to put them in a pot no bigger than an inch over their root ball. Or if it's a node, like 2" max. Maybe just pull it away from the humidifier so it can transpire more. How frequently are you watering it.
1 gilla I guess the other question is... did it come with the slight yellowing at the tips or is that new? For the fungal, just spritz/wipe down with 1:3 parts peroxide:water every 3 days for 3x. All the leaves
1 gilla Ok thank you so much for your advice. The plant did not come with the yellowing tips. I found a piece of foil stuck to the bottom of the nursery pot! Maybe that’s what it’s from! I honestly haven’t watered it once yet because it was pretty moist when I received the plant.
0 gillningar Foil wouldn't cause this, like no chemical reaction. It it was stopping water from draining, maybe. Mmm so they may have over watered it before hand. You may need to ammend the soil so it doesnt stay as wet
