I thought I would take a peek at your grow and offer any advice that may help.
One thing I can tell you is this. Some of these stalks are strong as fuck and hard to bend and if you push them too far they will snap. I have found a way to do it though.
What you do is pinch the stalk where you want the bend until you squeeze about half way through, then bend it over, if the outter bark splits a bit no worries, it will heal. If you do it right the plant will form an elbow and start to grow sideways, then it is much easier to keep it growing that way. If you don't pinch and bend it enough it will straighten back up. If you pinch it too much it will slow growth down a bit but come back. If you squish it down to nothing, well you just topped it.
Try it on the one extra plant you have. It really works great.
