What's up big red .now I am far from a pro by all means.first set of question for you is. What kind of lighting are you using, also what soil and nutes are you using.it could be many different Things.the reason I am asking about lighting is the distance you have between nodes.a good cfl 100 watt equivalent. Bulb does great for me, and very inexpensive.it helps to keep nodes closer together making your plant less stretchy.now for the color of your stem.it could be a characteristic of the strain.or it could be a deficiency ,possibly magnesium. It wouldn't hurt at all to add 1 tablespoon Of Epsom salt to a gallon of water and add to soil. New growth should have the green color after a couple days
