the slower starter has started to catch up but yet to top.
Other two seem to be growing nicely, tied down and a nice flat top.
Anything to worry about with some of the lower leaves? It's almost a whiteness in the middle of a couple of lower fan leaves
They start slow but turn out great. My outdoor grow last year started stretching really well from the 4th week. Don't underestimate those Sativa genetics 😁
