Hauspflanze Frage – Warum wird die Spitze des Blattes braun? Danke

I’ve had this with my snake plant, seems to be inconsistent watering. When I looked it up either too much watering or too little can cause it. They’re quite drought resistant and don’t need much water. I tend to ignore mine now and every few months give it a good dunk for a few hours and then leave it alone again, and it seems to be fine.
