Yes you indeed had a serious infestation. Once those larvae get a taste for roots they're off to the races. The roots become weaker as the stagnant water suffocates them. Free lunch. Personally I hate all commercial potting soils. There are many threads in this forum dealing with this issue, but if I'm going commercial I will only use the best. Screw cost; you get what you pay for. But in the event that you simply cannot find good soil like Foxfarm, just make sure that you're letting the soil dry out a bit before watering again.

In nature there is a limitless soil horizon around each plant and water can diffuse away. In a pot things are much more restricted and problematic.
