  1. what does it mean if the stalks of my cannabis plants are starting to get purple in them? and does anyone know a quick and easy way to get rid of fungus gnats?they are just starting, and are spreading fast. i am letting my plants dry out before watering in order to get rid of them.
     
  2. Purple stock can be many factors nothing to worry about unless your stock feel especially soft. They are many natural ways to get rid of fungus nats. Yellow traps, neem oil, Gnatrol, and Diatomaceous Earth all cheap and on amazon.

  3. The purple could be genetic, or it could be a phosphorous deficiency.
