Browning on leaves, light burn?

New here and looking for help. 2nd grow but first time seeing these spots. The light is about 15 inches from the top of the plant. I took two photos one of a leaf about 20 inches from the light and another about 36 inches away, both seem to be experiencing the same issue. I water at pH 6.5 and my run off is measuring about the same. Is this light burn or something else?
Molybdenum deficiencies??

Also, I moved these from the garage to a bedroom 3 days ago so they are getting optimum temperature. The garage was about 15-20 degrees cooler.

Tent. 3x1.5x5.5
Light. King plus Led 600watt
Soil. Oceans forest, fox farm
Strain. Auto fem blueberry
Neutrient. Foxfarm 3 bottle combo at 1/4 strength
based on suggested soil schedule.
Age. 7 weeks from germination
Schedule. Nutrients given 3 days ago
Temp. 70-78 inside tent
Humidity. 45-50 inside tent


Thanks

Also.... I noticed a nutrient burn at 1/2 so that's why I'm doing 1/4
