Your plant is still a baby. You can find some funny weird growth sometimes with seeds when you pop them. Take a look at my HSO Purple Trainwreck diary in the 1st couple of weeks. She had ugly growth. I even put 1 outside thinking the seeds were messed up. They're growing perfectly fine now and the 1 outside is almost done flowering. I've learnt to let seeds grow atleast 4 nodes before judging if it's bad genetics, bad quality seeds or they just need time, love and attention.
