@Silky_smooth The girls look great!! I will have to try this technique out once I get my room set up. Keep up the good work and keep the bud porn coming
If in fact that the super lemon haze grew a fan leaf on top then you need to top it. Cut it just above the first node and it will produce 2 main stems. It will slow it down a bit but you will be better off at the end of season
Not sure if they still do but back when their grow guide came out they said most of the time they run 24/0.

A 10 gallon pot is over kill for autos. From what I have seen a 5 gallon pot is big enough and you won't gain anything by going bigger. Just my 2 cents.
What kind of lights are you using cause the high powered/ high intensity lights will produce a thicker stem...once you move them outside they will thicken up for you. In the mean time I would gradually pinch your girls between every stretched node...not too much at once.
