Burns caused by drops of water. They act as a solar lens under the lights, only water when you are about to turn them off.

My guess is some water or dew formed there and your lights burned your girl a bit. They look very healthy otherwise!! Happy growing!

I believe I light burned my plants when I put in my second 300W LED. Plant's yellowing on tops and drooping and canoeing. Have just switched to 12/12 light 4 days ago. And started to feed Flowering mix of 9ml pure blend pro and 1.5ml cal-mag per 4L. Feed every water.

Late Flowering Stage Deficiency or Nutrient Burn
I'm not sure if this is nutrient burn or some sort of deficiency. Burnt tips were from possible previous nutrient burn, but now I'm seeing Brown spots and some discoloration. Please check my week to see full details.

Brown spots on tips of some leaves
4 leaves affected on only one plant. All plants are receiving same feeding and are from same clones. Based on photo and googling it looks awfully lot like P deficiency? I'm still in vegetation phase though. I'm feeding with Advanced Hydroponics Grow + Bloom + Micro based on chart

Condensation, CalMag, Nute Splash?
Twice between heavy defoliations the were leaves were so jammed together some leaves would get wet from contact with other leaves. It's the only leaf on the whole plant like this - as of now. Seems like Calmag? Product of sweating? Nute splash? (week 7 photos)
