To attack it from a different angle - If I had only watered the coco once per day (let's assume it doesn't dry out), wouldn't the root mass have been more developed?
Well, let's put it this way. Cannabis growers generally treat root growth religiously, because they know it's the key to exponential growth and yield. Your plants won't grow any bigger and yield any better than the root system allows.
Now, here comes along a medium with great absorption/aerating qualities, and with a CEC that goes beyond all peat based mediums, and suddenly a less volyminous root system seems to be able to sustain a bigger plant.
It means that as a grower, you'll have to re-think, and re-calculate your volumes. A plant's root system will continue to develop and spread, up until a point in flower where growth stops. If your root system hasn't filled up the pot by then, then it's probably because it didn't have time to do it in relation to the needs of the plant.
If you would have watered less, then perhaps the roots would have spread further in search for more water. But... what would be the point, if there was no need?

You can run your coco plants on BioBizz ferts. I treat my motherplants in coco with BioBizz, works like a charm. Growth is slower than with mineral based ferts, apart from that no issues.
