I've recently repotted my spider plant (chlorophytum comosum) to a slightly bigger pot with better drainage. I potted it in a mix of normal potting soil and perlite to aid drainage. I recently noticed that some of the tips in the lowest leaves have burnt. This is something that hadn't happened before.
- Could the perlite in the new mix have caused this?
- Should I repot the plant into fresh soil?
- Is this condition a threat to the health of my plant?
