Whats wrong with this girl?

Checked my autoflower girl and shes got rust spots any info on what the problem may be or how to fix her? Cal-mag maybe??

Those leaves are going to die off soon...don't use them as a road map for the future of the plant. Keep your eyes on the new growth at this point. The plant looks fine....however, what are the white specs on top of the leaves? (second pic)...be sure they aren't pests. Otherwise, don't over think things. You're fine. Good luck.

Im just worried that the plant is lacking something and thats what is causing the spots and i dont want it to get worse or possibly spread..and the spots are just perilite dust

It's so little it's not possible to really say if it's something or not.

But are those the first set of leaves? As CannaCountry said, keep checking the newer ones for signs, because it's looks healthy to me
