Small or is she about to take off ? any1 please with GC experience lol..

Growth is just spread around. it's already taking off. If you want a bit more stretch between growth nodes, raise the light 1-2" and use that as new distance until end. your spacing looks fine, but it's something you observe and adjust to as it goes vertically. Might end up with a bit of congestion in the central areas. Keep training it outward a bit longer if you don't want to selectively prune to thin it out. Look at how many 'vertical' colas you'll have and plan it out... make sure they each have some space for leaf growth. A jam-packed canopy may look good in pictures, but it's not the wisest way to go. you got 8-9 branches off main trunk and some axillary branching off those. Might get a bit congested in central area in the next few weeks without a little more training to spread it out.
