Topped all 3 plants above their 4th nodes on 12/10 and 12/12. Wedding glue is about 2 days behind the others, and Black Runtz is currently the tallest at about 11 inches.
These are all shorter than average compared to my other grows, and typically for my other grows flowering has started by now also, so I am thinking that the cooler weather a couple weeks ago slowed them down a bit.
Black runtz is showing some curling up of the sides of the leaves, so I reduced the light time from 20 hours per day back down to only 18 hours per day, also because it isn't too cold outside anymore.
