This little fella sprouted a couple of weeks ago. As you can see, the tip of the little leaf turned brown. I "guessed" this was from it getting too much sun/heat and have moved it a little further from the window. I know tho, that I could be totally wrong. So:
Can anyone tell me how much water and light it should be getting at this point? Should it be fertilized? I can't move it out doors for a few more weeks. It's about 1 1/2 inches tall. It's musa sikkimensis.

Many thanks!
