Verry Nice Lookin pups Mate....

If I was to critisise..
I would say get em in Larger pots in a good Poting Mix before they go to Bud.(asap).
I have done grows In Pots the same size as in your second pic.
and from what I have experianced the roots need more space
They will still Be Nice Dont get me wrong.
But They will Reach their Full Potential in larger Pots.....
My absolute Minimum nowdays is 20ltr Buckets.
with Good drainige holes Drilled in the Bottom of course..
