I think sometimes you do get the odd plant that has genetic annomalies. Not necessarily BAD genetics though. You dont really know wether they are bad or good annomalies until you flower the plant. If it has a strange number of leaf points all over the plant, id say its probably genetic. If it only happens to a few leaves, more likley its been caused by maybe stress or just the way that plant develops. All seeds are individuals and will display differences but I'd personally want to grow the 'wierd' plants more out of curiosity.
