Welcome to the forum, great people around to help you.
Girls look great, new growth, good color. Off to a great start IMO.
It will be awhile before you see big growth, girls will take awhile to dig roots into that big of a container, once she does, take off time.
Where is your temp and RH gauge?
I highly recommend reading this grow guide, am a new grower, and doing better than expected following his methods. He covers everything and then some, experiments, you name it!
