budda420answered grow question 4 years ago (Im a newbie my self but this is just my opinion from what I've read) i just had a look at your diary and it says in week 2 you wanted to transplant, did you actually transplant these girls? If so that could be another reason they are stunted nothing to do with the LST autoflowers should be planted into there final container as they dont take to stress very well aslo topping is not recommended for autos either unless you know they are going to be some quick growing big girls, just my 2cents, hope this helps in future good luck dude
