Fungus Gnats or something else?

Hey All,

I have these lime green/copper brown spots on the lower fan leaves of one of my plants. I have had pH issues in the past and this looks different.

I have 13 6-week old plants growing from bagseed in soil. I started fertilizing at 4 weeks with a weak dose of Age Old Grow 12-6-6. Then a week later fed again with slightly stronger dose + Cal-Mag.

I have been having issues with fungus gnats flying around for the last 6 weeks, and from what I've been reading, they might be attacking the roots of this plant. But then why just her? Or is she just more sensitive? Does it look like a pH/deficiency issue after all?

I don't want to lose her. Thanks for whatever help you may offer. :peace:
