My outdoor auto plant did not do shit for a month after it sprouted. Just sat there as a 2-3 inch sapling then finally put on some growth. Autos kinda do what they do and there is not much you can do about it and they don't have the same consistency as there is with photos, if you got a runt you got a runt and there's not much to be done about it. The smoke should still be about the same quality that her sisters will yield just less. Your plant looks health so no reason to change your feeding unless she starts to show deficiency
