I'm having the same issues here and there with veg bro. It's wierd though, once I get the plants under hid lighting they are nice, but working with t5 or low light hid, I've been having problems. I actually just threw away 10 15" glue plants today because they weren't up to standards. They started growing healthy, but I have to flower at 15" because my tents are only 6.5' tall, so I cut them way back to promote branching, well they branched a bit, but then I was left with a bunch of healthy small nodes, not branches and they were back to 15", no point in cutting those back because then it would be just branches with little nodes and no tops lol. Just wasn't going to flower right at all. So instead of wasting time with those I have 10 5" glue clones well rooted that I already trained to have 5+ branches so I potted those up and in 2 weeks they'll be better than flowering the other mangled plants. I don't really have to train em at all, just let em grow for a bit then flower. It sucks when I have a plant height restriction for flower, sucks more when some plants have 6" of stem before the branches begin, feels like after the move I should have just thrown out a lot of plants that turned to shit rather than spending time and $ trying to save em then throw em out anyway haha
