Just water

My first thoughts Looking at the pictures the flash did not cause this problem I would start by checking my PPM runoff. As mentioned looks like nute burn.

Did you wash plant down under lights and leave them on for an hour or more? That would do it.

Nothing you can do: the light burned the leaves due to ‘lensing’ and will not recover. If spraying plant it’s best to do just before lights out and put a big fan on it. I’m not a big fan of foliar anything except to control pests or fungus.

Plant will survive and it’s a ‘live and learn’ moment.
