It is either a low P deficiency or low temperatures can cause this purple color to appear and finally a really low humidity level can cause things to purple.

A great additive to use is Mag-Pro by Dyna-gro, its NPK is 2-15-4

It is SUPER clean and SUPER concentrated so you use very little with dosages.
Hope this helps

[/quote]Soil pH as low as 5.5 will also do it, and its not a good thing.

I also have 3 clones 12" high looking great but they are headed down the same path the 1 with 5.55ph is 1 of the another 1 is 5.05 and 5.95 ppm for those 2 are over 2000 from just the soil added 1tsp lime to each last watering hope that helps
