First grow. Do these plants look ok for day 40?. I have a few pictures but it’s hard to see, I have 2 leaves that have a couple spots that look like rust, what is this and what would cause it.
Not knowing anything about your grow it is impossible to diagnose.
Frankly; plants look just fine.

White widow autos. 2x2 tent inline fan with filter.
Fox farm ocean garden and Coco loco 50/50 mix
Spider farmer sf1000 light and a bestva 1000 blurple. Bergman nutrients currently feeding at 600ppm. Tested run off this morning and had pH of 6.4 and 1800 ppm. Very little tip burn, I just upped their ppm when feeding from 400 to 600. Just wondering if the rusty looking spots where.

I think you are fine.
FYI coco tends to sequester calcium so a dose of cal mag might not be a bad idea.
With a runoff TDS of 1,800 ppm you could just run water/cal mag until the runoff hits 1,000 ppm then resume feeding at 1,100 ppm or so.
Whatever you have is very minor so take the above with a grain of salt: plants look fine.
