It's never happened to me but I've been told it happens to some strains.
Some plants turn different colors naturally, without cold temps.
A nutrient imbalance can also cause a color change.
Speaking for myself, I couldn't care less what color the bud is, as long as it gets me where I want to go.
~hmm.......... any idea of wich strains change on their own?? Or better yet what do you recomend? i always enjoy something spicy w/ a shrap creeper high,. We get first frost as early as mid setember = ( And inside i stick with indica dominents), so i guesse do you know of any exceptional early sativas?
or any favs you have.
