guys! the lower stocks of my dracaena marginata are not doing too well. the leaves are falling off (only on the lower trunks?). it was getting some direct sunlight during the morning and bright indirect sunlight throughout the day so thought it might be needing more sunlight so I moved it to my living room but alas it doesn't seem to be helping. I water ~2xs a month since it doesn't get a ton of direct light.
I watered my cactus last night, and this mold looking pest literally grew on one of the stocks over night! I already separated it from the other stock and threw it out, but WOW! I need help to diagnose so I can take care of the other stock.
