All plants inside need as much light as possible. Even though it may look bright to you and I, to plants, these are dark places. The do, after all, run on light. A few saggy leaves at the base could be a lot of things. Did you recently transplant? that alone could shock it a bit.

No, I have not recently transplanted it. Could it be that it is to cold for the plant? I live in New Zealand and it changing to winter here. I also might move it to a brighter place. When watering, I water the plant when the top layer of the soil starts to dry out, but underneath is still moist. Could this be the problem? Thanks.

Yes, you might be watering just a bit too frequently-an extremely common occurrence. also, by all means do provide it as much light as possible indoors. Even bright rooms indoors are dim compared to even under a large shade tree outside.

BTW, for the most part, your plant looks great.
