Have some clones to determine sex, (they are in flowering) and some of the stems that attach the leaves to the stem is turning purple. is this a deficiency?
Most of the time redish purple stems are not a cause for too much concern but the plants need to be watched for any other signs that could match up to a deficiency. Purple discoloring of the main stems, leaf stems, and the veins of the undersides of the leafs could be caused by a few things and could also just be normal genetics. Most of the time I have found it to be cause by dark period temps to be dropping down too low (more than 15 degrees F). A phosphorus (P) deficiency can also be the cause if the leaves are starting to turn dark with a bluish green tint. If interveinal yellowing is starting to occur along with the purpling stems then it could be either a Nitrogen (N) or Sulfer (S) deficiency. If the above is not occuring everything is fine.
