my plants are 55cm tall both of them one is like a christmas tree nice and bushy,the other one i toped and its branches have soared nearly beside the main tops but its not bushy both look nice and both are female the one i toped had real problems for the first 3/4 weeks but took off after topping i dont know the strain but are thay to small for the age thay are both in 11l pots is it to late to transplant them or will it be ok,,,

Yes, it is too small, and all the girls are going to laugh at you.

Pictures are always pretty awesome
