Possible nute burn? Brown spots developing. Help please!

[ShinGimmel]

Hey guys, new here but I'm planning on being a pretty big member of the community from here on out. My first baby girl has developed some spots on her that I'm a little worried about, it seems to be the only leaf of the plant with the spots on her; any help would be greatly appreciated!

Growing in soil:

Single bagseed plant, so I can't really be sure on the strain; looks like there is indica in there somewhere.
Shes in vegetative right now, I'm about to increase the size of her pot. She's under CFLs and has been loving it so far.
I water her with PH corrected water, try to get around 6.3 normally. Room is kept between 75-83 degrees.
She's got fans on her and everything, and no signs of an insect infestation.

This is a beauty shot, she seemed to be doing pretty well.

These are the brown spots on her, I've no idea what they're from.

Calcium or nitrogen maybe?

Go check this page and see if any look like yours since I can't see them and you can.

Tried to fix the pictures; from the link it does look like nute burn, should I flush the soil a few times to try to remove some nutrients?

Your leaf tips arent showing toxicity. Your newest growth isnt clawing. It looks like that one fan leaf. Looks like nutrient or water splash accidental that formed a mirror effect when light was introduced.

Thank you so much. That is totally possible and I didn't even think about it. I love this place.
