Two weeks into budding, one plant is leaning after feeding, any thoughts?

Ok, so my girls are 2 weeks into flowering. When I got home from vacation last week i noticed one of them was leaning heaily to the side... like it was extremely sad, so I tied her up and she was doing fine once again. Today I added a tablespoon of Mollasses in with my nutes and the damn plant has started to lean again.. I am thinking that maybe the extra weight from the molasses is weighing down the buds..... but then what is going to happen when these buds start getting more dense? Trying to figure out what the deal is... I have a 400 Watt HPS in a 5ftx2 1/2ft grow rom that is plenty tall, Mylar covers the walls in the room... Any sugestions?

The girls seemed to have loved the molasses, just added 1 tbls per gallon along with nutes. The other branches seemed to have fallen to places where they get better light, but the two main nodes are still just a tad unstable, am i missing something here?

Man don't sweat it. Some strains are famous for this(trainwreck etc.). Thats what Scrogs for. Just keep tying them up and if you continue with this strain consider scroging them.
