Looks pretty good. But...(and this is not at all a complaint)
Did you by chance give some veg ferts (a nitrogen source) in an effort to green 'em up? Just wondering, because the growing tips seem stretched a tad. In the Fox Farms schedule it recommends that after you switch to 12/12, to wait a couple of weeks and add a couple of doses of veg ferts. This get's them stretching again, (just a few inches or so) which will eventually fill-in nicely. A technique I use myself. :thumbsup:

Also, are you watering deep enough to reach the lower root zones? The topped plant looks a tad thirsty. As the foliage fills-in, it will require more water. Speaking of which, have you tried growing 'em with straight tap water? Unless it's exceptionally crappy, ph adjusted tap is usually fine for soil grows.

I learned to grow cannabis using MG potting soils, despite it's having a bad rap for years. I guess folklore trumps success stories, because the shit works great if you figure it's nutes into the equation, and adjust accordingly.

I'd smoke 'em. :jointsmile:
