White stuff in my house plant's soil
I am very new to caring for plants, so I'm not sure about much. But since moving into my new apartment, I have been noticing more and more white chunks of something mysterious in my soil.... I have no idea what this is, if its normal, or if it could be harmful for my plants. if I were to describe it, they would look like grainy white rocks, but some of them feel a bit spongy..
all information is greatly appreciated.
