To Prune or Not to Prune....that's my question anyway

I'm getting mixed reviews in another forum. Thought I would try here. One poster suggested trimming 1/3 up the bottom over the next few days. Another poster said to leave them be. They are 2 weeks into flower and they are white widow. It's my first attempt in this space so I just guessed at the number. Part of me has been thinking of taking out 2 of the plants or to trim them to allow for more light penetration. At some point in the next week I will take a stab at putting in some T5's along the wall or something.
