Hello all!
I bought this banana plant a couple of months ago, and it was doing okay. It was in a tiny pot, so I repotted into a much larger one and used some Miracle Gro potting mix with fertilizer (probably not the best stuff in the world). It sprouted a new leaf very quickly, but then all of the sudden ALL of the lower leave wilted away and died, leaving only two leaves left. Now both of these leaves are dying (showing brown on the tips) and a new "shoot" also shows signs of brown that indicate it is not healthy. I have posted images here:

If anyone can help me diagnose the problem, I would very much appreciate it! Thank you for reading!
