Sick super dwarf cavendish?

Hi, I've had this banana since 2011 May, during the summer months it was growing really nicely, because it could spend the days outside, in the sun. Then it was brought inside in September, and around until the middle of October it was growing OK, but then as the days got shorter and shorter it started growing one leaf after another before the previous one was fully unwrapped as opposed to one at a time. It got so bad, that we've decided two weeks ago to set up artificial lighting for it. We stood it under 4x18W fluorescent T8, 6500K(cool daylight) lighting, and I thought that the plant should fix itself after about a week (because usually things happen quickly under artificial lighting with other plants for me), but it seems like it has done nothing since then.
My ideas: it can't put out new leaves because it's choking, and two less believable: bunchy top virus (due to the bunching of the leaves, although no chlorosis and I don't know how the virus would get so up north) or it's blooming and chocking.
Take a look:
  
bunching of the leaves:
Three or four immature leaves at once:
Mystical hole:
And the most important - the bump which I believe may soon be the escape for leaves that can't be pushed out normally:
What should I do? Should I "operate" it? How would I need to do that? |

| Interesting problem. I have never seen this before. I wonder if it is a light, temperature or nutrient issue? I guess you could take a razor blade and cut it off right at the bump or made just make a slice parallel to the stop from the top to just below the bump and that might allow the leafs to push out. How deep do you need to make the cut is the question? Definitely don't want to cut the center portion. I posted a video of some surgery that I did on a small pup to get the center leaf growing an stop the rot. |

Although I noticed that the newest leaf is growing, so maybe it's not stuck, and I don't need to cut it...
Maybe the pot is too small, right now it's growing in a 34cm diameter, 12l (4gal) pot, we're going to replant it into a larger pot in February, maybe it'll help a bit, and we'll make the substrate more porous by adding perlite and pine bark, because it is currently growing in pure peat. |
