Simple to solve by adding a bit more soil so that more of the stem is buried and no more bending!
Also, for the sake of your plants, go to 18/6, plants NEED sleep to finish their photosynthesis cycle and to have a correctly functioning metabolism. A plant with an incorrectly functioning metabolism will never produce healthy cannabinoids.
24/0 could only be recommended by growers who do not understand photosynthesis or how plants function, or maybe both principles.
You will not lose anything by going to 18/6, in fact you will gain much due to your plant having a correctly functioning metabolism and being able to grow how it has evolved to do.
Nothing on planet Earth can survive in peak health when subjected to weeks/months without sleep.
Hope this helps, Organoman.
