I don't know anything about this strain but i'll throw in my 2 cents. The buds are coming along, sure a little slow but the thin look of the leaves makes me think there could be strong sativa genetics in that plant which may cause it to take a very long time to finish. as for the purple color the few plants I have had turn purple only did so during the last 3 weeks of flowering, so it could still happen don't give up. If you really want purple buds try using purple maxx they claim 1/3 of all plants will purple with use but I dont know how good it really works.
