Why do I keep seeing everyone refer to DJ SHorts Grape KRUSH as Grape KUSH!?!? (without the R in Krush) It's driving me nuts!

I have a strain of Grape Kush that is OG Kush x Grape Ape - It is called Grape Kush.
Another name for the same Grape Kush cross is Kings Kush.

If anyone has any more info about the grape KUSH strain please chime in...

People need to set the record straight - DJ Shorts Grape KRUSH is not Grape Kush!
