Too much water, not enough water, not enough sunlight, or low levels of nitrogen in the soil.

Too much water? Not enough water? Some sort of disease?
Reply:Check for white flies, also put a 1/4 cup of epsom salts with some timed fertilizer around the base of the plant, scratch it in and water well. If you are in a warm area and it is above freezing now, otherwise wait a bit. If you have flies you will need an insecticide to spray with.
