The bottom older leaves are starting to wilt and most of the leaves are showing these white silvery spots that look dried out more than the other sections of the leaf. I am growing indoors under led lights.

Just red light? No blue light? Blue light is essential for photosynthesis. Your plants are living in the dark.

No, the light i am currently using has blue and red spectrum. I have both blue and red on to give it a full spectrum. I have grown plants with that light before like this so I know they get enough light. It is something else that is causing this. I have noticed darker sections of my broccoli leaves as well now.

Older leaves on tomatoes, starting at bottom, just naturally die off.

Silver/white on leaves, maybe mildew. Does it wipe off ? Then, I'd say mildew.
Anything i say, could be misrepresented, or wrong.
