I agree with Canefan...... no need to directly flush the soil. Just use plain water the last week or two, to keep your plant hydrated and let the plant use up what's in the soil / stored in the plant.

A sure sign this is happening, your older fan leaves will yellow and drop or pull off easily. Then you know, some smooth tasting smoke lies ahead.

Keep it Real...Organic... & don't fear the yellowing fan leaves.......
