There are a couple types of brown- the dry, flaky, light-colored brown which is just bark (yup, cannabis grows bark when it is old enough!) and a darker, wetter-looking, more sinister brown tht comes from fungus.
If it's flaky, don't fret.
stinkyattic Reviewed by stinkyattic on . Question: Stem turning brown(ish) color. Hi i have a question... i'm 27 days into flowering, i'm getting lots of buds starting to appear with nice big green flat leaves. what i have started to see is the stems of are starting to turn slightly brownish rather than the light green they have been up until now. is that normal?

I have pics of the what the plants look like as a whole here on this other thread "http://boards.cannabis.com/indoor-growing/158726-new-grower-15-days-into-flowering.html" Any Rating: 5
