I agree with Blocc420. Judging by your profile you know what you're doing..
If they're new seeds, then I'd contact the breeder.. 1 out of 10 is really bad for their reputation. They'd have to look at the batch of seeds where yours are from, or risk losing a lot of costumers.
- If they aren't new seeds however. You might have fucked up with storing them. And nothing breeder can do about that.
