Trying out my new SGROG technique but ran into an issue. Lost one plant already and now the second one is going. Notice the narrow stem, its like getting pinch off in the middle. The plant I lost got so top heavy it just bent over from the pinch off area in the middle of the stem.

Any ideas on what is causing this or what I am doing wrong??

Is it from my previous trimming and some bad mojo got into the stem from trimming??
