I water the entire pot until it runs off. The stuff described above is, wait for it, over, that's right, over watering. Overwatering comes in two varieties. 1. flushing your plant too often; this leads to rot and nutrient starvation or burns depending on medium and solution offered. 2. Watering intervals to close together (watering in a tiny circle). Both lead to all kinds of issues. Water your plant edge to edge, every time, until it drips, then drain completely. This should give you about 1/5 to 1/4 runoff (20%).
