New growth, getting bigger and taller looking greener?
Post a pic if you can of the progress.
If it ain't broke don't fix it lol I would just chill a bit and start a light nute regimen when plant says so.........check out tip top toker's post up there he suggests no nutes till 4 inches or so thats good info right there I would say its going to be a few nodes till plant shows any signs of def's but you say plant seems happy now you be happy for the moment lol.
