Naa don't prune leaves off that are good. Just bend them out of the way. First harvest the top fat buds then let it go for a bit while the lower ones swell for some nice bottom buds to then harvest that. That will maximize yield. As far as the extra light the cold spell it over and I cant handle the heat of both right now so just hps and some rotation and leaf bending. 2 plants under a 400watt HPS is pretty good as far a light availability. Im going to feed them up until harvest since im going to try a water cure...I may flush a little though.

I like to harvest around 15% amber.
