Sounds similar to a problem I had with one of mine few weeks ago. I was getting wet brown spots on a new basjoo that I had potted up outdoors. Is it a new plant with a relativley small root system? If so, it might be overwatered. If it's actively transpiring water from the leaves I'd let the soil dry out a little more between watering and see if that helps.

If it's an older plant and has been potted indoors for a while it could be that the soils ph is at an unacceptable level and the primary nutrients are locked up. Excess fertilizer will eventually build up in potted plants and raise the ph, which locks up all available nutrients and will cause a deficiency depsite the fact that you have added more than enough N-P-K.

So if it's a new plant I'd try watering less. If it's an older established plant I'd try watering less, but when you do water really flush out the soil so that a lot of water comes through the drain hole (think gallons)...this will flush out excess fertilizer and salts and restore a more neutral ph.

good luck
