...heat/light stress.

ok, must be previous damage before I fixed the temp issue, temps were at 83, I was able to drop the temps to a cool 75.

What exactly is light stress?

...your light was possibly too close, cooking the foilage. What kind of light setup are you using? ....and how close was the bulb?
