Add some coffee ground, a circle round the main root once every 3-4 weeks. Or banana peel water 2-3 times a week max. (leave a banana peel in water for 2-3 days) for nutrtional value. But not too much of any, you can get away with the peels more because their lower dosage.
Remember to ensure good drainage of pot and tray at all times and always soil test to then gage/schedule how quickly your plant needs more water. If dry, water all the soil and drain the excess from pot and tray at all times. If wet/damp leave it alone! Keep near the window sunny/warm. Good luck!
