Hi, where is her stm? did you dig hr deeper=?....but back to your question... i would rise the lights to give her more internodal space, if the lights are to strong/ to near the plant " dwarfes " under the light. just rise and she will stretch.Ive grown a number of automatics, and tried a few things. my experience says go wtih topping ( after 3rd node earliest) and Lst. All Plants respond very well to LST and you sont stunt her in growth. You can do more if your plant grows very vigor, but i would look how she tends to grow. So far everything looks good, she sits in final pot, filled with fluffy soil. Thats very importnt fact. iam following up to look how she spreads... happy growing
