No. What this does is give you stronger bud. You get less but it is more intense. If you grow lots of plants it's okay to pick the weakest and try out little experiments.
Basically any stress you give your plants during flower will cause the thc production to rise, although this would then use less energy for growing weight and density to the bud. Too much and you can hermie the plant which is why most growers opt to do it just a few days before harvest.
A clever way to increase thc production without losing too much in weight is to trim your bud just a few days before harvest. Leave on all the big fan leaves and trim the rest of the bud like you would had you harvested. The buds will tighten up fairly quickly and thc production will intensify. Although, I only did this once.
It's about experimentation. I'm the kind of guy that can't take other people's word for it, I must find it for myself.
