I think your logic makes sense actually. The one thing you want to be aware of is that -how do I explain this- your water carries the chemicals (nutes that you give it plus whatever it picks up from the soil) with it. The plant uses a certain amount of water plus a certain amount of the chemicals. Not all. Eventually, there will be an imbalance from the leftover stuff. This is why DRENCHING the soil to the point where some water runs out the holes, about once every week or 2, makes sense. These excess salts get flushed out so they do not harm the plants.
Many experienced indoor growers will give a good drench weekly, then a couple light waterings in between as individual pots start to feel light.
