Typically when I see rust on a plant I lean towards thinking a magnesium deficiency. The rust is the result of the plant remobilizing Mg from older leaves to new growth. I kind of see that here, but I also kind of don't.
I think you may be feeding a bit heavy or the soil is hot. I'd be interested in knowing how much you're feeding, what type of water source you're using, and whether you're measuring things closely and know ec/ppm's

Mag shows at the bottom leaves like that calcium usually upper leaves starting with white spots.

Looks like too much fertilizer is building up. Thick shiny leaves and now deficiencies showing down low.

I would run some fresh water through. Then lower the concentration of nutes.

Should reset the medium.

Shiny leaves might be from neem spraying but like i said i only been using flora gro its not a full nutrient its part of a 2 step and is the the weaker of the 2 i think but just incase i did feed with alot of plain water before feeding some mega crop i got today
