strong stem, small growth in height

Its actully a good thin you have really good internode spacing there she will be a nice ribust bushy plant as soon as you flip her which depending on the size of your tent I would look at doing soon otherwise she might get too large to control in my experience the runtz of the litters so to speak always turn out the best lol its what ive found anyway lol shes very lovely shade of green thats what you should be chasing thats almost optimal plant health in my opinion if its wasnt an auto i would suggest defoliation but she is so just let her go im sure you will be suprised being an auto in the first few weeks of flower whenever they go they tend to explode anyway :) in a few weeks this will be a different plant suprised to see no pistils yet but thats another good thing :)
