Is my plant dying??? can she be saved?

My plant is about 3 weeks old, planted in miracle gro potting mix (I know, terrible). About 3 days ago I sprayed water on her and had this white film over it since, I thought that it could have been water spots but i've tried cleaning it with multiple methods (raw acv, warm water and q tips, etc) i'm starting to thing its mold but don't want to jump to conclusions what should I do??

Thanks in advance

Your plant is fine, man. Like you first suspected, the little bit of white I can see on the end of the leaves in maybe 2 of the pics looks like salt, not mold. Your plant is not dying, and doesn't even need "saving". Keep calm, and grow on

Its nothing ... Just leave her

Looks fine to me.

Thanks for replying guys, I don't think those photos captured what I see too well, here:

light burn maybe from the leaves getting wet

could be the start of a bug problem but as long as you use something to keep that under control in a few weeks it`ll be ok... just let it grow a bit more and try not to spill any water or chemicals on it
