Some clarification would be appreciated here. Absent other symptoms of too much light intensity, is this necessarily an indication of an issue or is this considered to be normal behavior for cannabis?If you notice on the second pic you are seeing purpling only on the stems exposed directly to high light and to further point out its light... that purpling is only on the light exposed areas.
This is caused by what's called anthocyanins and is a direct result from intense light. Usually in places that don't photosynthesize as well like your stems.
Reason i raise this question is I've always been under the belief that purple top-sided petioles and purple veining in the stalks is normal -- that's a consequence of the light intensities when indoors. Again, absent other symptoms like leaf taco'ing, bleaching,similar symptoms to transpiration constipation or overwatering, etc. should one be mindful of this?
Now that my inebriated brain is thinking about this, this topic could likely warrant an entirely separate, topic-specific thread, but just looking for a high level yes or no answer here.
