Thank you @mangopie!
You have a really good eye, the mack's are indeed producing unprecedented levels of resin and are really starting to release pleasantly heavy aromas.

I overfed them a little a couple of weeks ago but quickly flushed them as soon as I saw the signs. The biggest plant (a MM) took the worst of it and might suffer a little production, but I'm happy nonetheless, they are pretty healthy and look promising at this point.

Happy new year to you as well my friend, I hope the new year meets you with success, happiness, and positivity in all directions!
