I'm a novice grower so I'aint got a lot of experience, my plant doubled the lateral branch, and I've never seen nothing like that, can someone help me? It happens?
Yes, these things happen once in a while and are not really an issue to be concerned over. Your plant has basically "topped" itself.
Just double check that an insect (caterpillar maybe?) hasn't taken to dining on your seedling.
Great clear and close up pictures in normal light are really appreciated!!!!!!!!!!
Hope this helps,.... Organoman.
