Cab temps rarely drop below 75 at night, and run around 80-82 during the day. They were taken from a flowering plant, and the stems are more of a purple. I am currently using two 2700k 30w cfls and one 30w 6500k cfl. I have two more sockets available but I am keeping the light week for the first week they are in the cabinet.

By pinching, do you mean topping the plants?
