I know but your problems comes from excess nutrients in the soils. And just watering it with water may help, but adding enzymes will help transforme the "sugar" in the soil so the plant can absorbe it correctly. Enzymes transforme organic matter into food for the plant, to make it simple. Less work for the plant. If this does not solve your problem, then it's a bacteria or disease or something else and your problem is out of my league.
