Anybody have issues with GreenHouse Seeds Bubba Kush??

Hey everyone. Just wondering if anyone else has had any issues with greenhouse seeds bubba kush and hermies. I am/was running a grow with 3 bubba kush from greenhouse and 3 pineapple express from G13. I am/was in week 3 of flowering and while inspecting my ladies I found pollen sacks on all 3 of my bubbas. They are fem seeds by the way. The 3 pineapple express plants are fine and starting to bud like crazy. None of the plants were stressed in anyway, I just find it wierd that all 3 bubbas hermied on me and the pineapples are all fine. Needless to say the 3 bubbas were chopped and disposed of last night, none of the sacks were open and they all seemed small and immature. They would have just popped up in the past couple days as I am a freak with my ladies and inspecting them. Anyone else have any issues? I have read of some germination problems but I am usually one of the people who say that 90% of the time it is grower and not the seed.

On the bright side the pineapple express plants are going to love all the extra light they are getting now.
