these white spots have been increasing in number over the last month or so. not sure what they are. and then the colour started fading from one of the leaves. i put a grow light to shine on the underside but we’ll see if that prevents further damage. could the white spots be a fungus? it gets most of its lighting from grow lights and seems to be doing fine. it even has a new growth. i just watered today because it was bone dry and then i put the globe in the soil. the globe is new so it couldn’t be because of that. any thoughts??
