Hi, I've seen this heaps in other species, so I've asked this question too

From memory, individual plants ability to draw chemicals such as magnesium can be a factor In changes like purple & blackish colour variations in many species of plants. It is very common on the seasonal change toward the cooler months when plants have a reduced ability to process the magnesium.
This can happen in part of a single tray of seedlings & can be effected by calcium deficient mix, further reducing magnesium uptake.

Someone else with more scientific knowledge than me might beable to explain that in better detail.
