Looks like the stretch will start soon, the gsc did show sex later then the rest but all is good, the
big blackberry is doing very well with the GHE, the biobizz is giving the gsc and northern lights some nice dark green color and they all look healthy besides calmag, i am applying foliar with calmag and its looking good, Overall happy and excited...
Day 28 the gsc got a little nute burn but still growing at a fast pace will only water later on as for growing, all of them made beautiful side branches except the mutant berry but that's out of my hands, will start with bloom nutes after the stretch and some decent preflowers, as for now only a few pistils here and there no clustering yet, coming week will show what they need, Overall happy.
you should look into hard lining for late game canopy leveling. 3rd to 4th node from the top, pinch the stem in the direction you want to bend, slowly bend at the pinch go slightly past the desired Hight by about an inch, as the plant will rebound itself upwards again
The northern lights blue from delicious seed started to hermie took her out, Must be luck of the draw, but the rest is all good at least the sacks didn't open so the rest of the lady's still good, didn't take a photo as i reacted fast and remove all of them she is in an isolated room for few days to see what she will do
