It's all good man. This is Purple Kush from the old SR71 club in SF .. now Blue Sky. It is the oaksterdam clone only version. There are a lot of purple strains out there, but the SR71 PK is my favorite. It doesn't get as purple as grand daddy, but IMHO is a higher grade smoke. There is a Vegas strain and a lot of the seed companies are comming out with their version of purple kush. Erkle if you can find the original clone only strain is bomb as well, but there are many strains out there being called Erkle that aren't the orignal. Watch for some stretchy plants with the GDP, it will get tall if you let it.
I would like to get my hands on some Jedi Kush, which is very close to pk, but yeilds are bigger and she turns a darker purple.
