Well, it sort of sounds like I'd expect it too.

I'd expect the WW to finish up up quicker and tighter than an "unknown bag sativa". If the plants are tagged, have a look and see if that's how it breaks down. If so, perfectly normal.

I'd also have a look and see if the stringier stuff is closer to the bulb and therefore growing at a higher temperature- high temps'll make a lot of things run.

If you're sure that it's the stuff closer to the door, then it'd be worth looking for light leaks.

Sounds like things are going well.
