Looking at the plants in the background, you seem to have a few yellow lower leaves which might be from N deficiency. The particular colors of the leaf in question do look like they were caused by cold, but I'm not sure.

My night time temps are like 64F at night, when lights on about 79-81F

Yeah I’ve had a few deficiency as first time using powerful LEDS but there starting to bounce best now, just need to know if I have to raise temps in there??

I would not raise lights out temps. Mine goes that low at lights out, too. And yeah, I've had a similar learning curve with LEDs. My current grow is the first since I switched where I provided enough nutrition for that dose of lighting.
