Why are my seedlings stem purple?
Purple strains with very dark foliage, for example, often develop purple stems too, especially if you grow them in slightly cooler temperatures. As long as your plants look otherwise healthy, there’s usually no reason to worry. Other than genetics, another major cause behind discoloured stems is strong light exposure.
Why are my leaf stems turning purple?
While purple coloration on stems and petioles can be one of the signs of magnesium deficiency in plants, it is also a sign that the plant is producing natural purple pigments (anthocyanin) in response to ultraviolet (UV) light.
What color should seedling stems be?

Why are some marijuana plant stems are purple?
Some marijuana strains naturally grow purple stems which cause their budding seedlings to seem even more “purplish” in colder temps in the dark. Other strains, especially those that show stems of seedlings that have turned purple, and have no other issues, have been genetically modified to do so.
