Weird white spots on pots of my cacti and succulents. Mold?
Hello everybody!
So I own a few cacti and succulents. Most of them are not affected and agree doing fine.
However, I noticed white spots appearing on the pots of don't of my plants, especially the smaller ones.
Some of my larger plants also have white spots on their pots, those are clearly limescale however, since the water where I live is very hard.
I attached some photos of my smaller plants, where the white spots look strange. I think they almost look like mold?
I water my succulents and cacti roughly 1x/week in summer. They are all in direct sunlight, either in South facing windows or on my with facing balcony. In wintertime I water less. The pictures are taken right after today's watering.
I've repotted all but one plant into a cactus substrate.
My question to you: what are these white spots? Are they mold? And what can I do about them?
Thank you in advance!
