Powdery mildew resistant strain?

Ive been having this problem lately...could someone recommend a strain which is resistant to PM?

Thnaks

I have an OG kush and Blue Dream in the same tiny 2X2 scrog tent the OG kush has had PM for 4 weeks and I have been controlling it with Serenade with mixed results. The blue dream is totally immune and the infected leaves are literally touching it. Moral of the stry Blue Dream is extremely PM resistant

oh wow - missed the year of your post, got the day right though..

Lol. Is Blue Dream clone only? If not, whish breeder do u recommend?
