Problema com a Cannabis

[Greatlionz]

My plant has a purplish tone inside the part where the flower will grow. I don't know what it could be... can someone help me?

Hard to tell from the photo but it looks like rot. The rest of the plant looks fine so I would just monitor it and see if it spreads to other sites.

What is the strain, some do purple.
