Spots on Leaves

[Whipoorwill]

Greetings farmers. I am growing White Widow Autos in a DWC system. I am in week eight (day 52). I am noticing rust colored spots and patches on a few leaves of one plant. I have attached some photos. It might be leaf septora, but I am a new grower and not experienced enough to be sure. Have you seen these before? Much thanks!

looks like powdery mildew to me.
