Heat stress vs light stress?

  1. I'm not sure if I had some heat stress issues a week ago but I raised my light and I still have a yellowing in the same leaves ( new so I'm not sure if they're supposed to stay like that or not ) but I also have 180 W LED combined with a 600 W HPS like three weeks into flowering. Is the LED combined with a 600 W like too much? When they started the light was about 9 inches ouch so I moved it back to 12 to 16" to about 12 inches away now. Not sure what I should do other then soon to start bringing the colas down with maybe fishing weight or something this is my first grow. Thanks to all the blades for the trick about taking the picture in flowering through your sunglass lenses it helps a lot. [​IMG]
