Hello everyone!!
This is my first time posting. I've grown 4 varieties of tomato plants from seed. I'm using a High Pressure Aeroponic system. Everything had been going well until recently. Below is a quick rundown of the grow room specs along with the issues I'm seeing. At this point I'm a bit stumped. Could this be due to overwatering?
Any help would be greatly appreciated!

Pic 1. Minor leaf curl with "leathery" texture
Pic 2. Significant leaf curl/twisting?
Pic 3. Leaf twisting
Pic 4. This variety looks very limp. Some branches have turned upside down.
Pic 5. Branches upside down. Limp.
Pic 6. Leaf curling up
Pic 7. White/tan spot. This might be sunburn from getting to close to the lamp?
Pic 8. Only 1 leaf on 1 plant like this. The leaf is black, dry, and almost dead
Pic 9. Closer look at black leaf
Pic 10. More leaf curl
Pic 11. White patches
Pic 12. Yellow splotches
Pic 13. White Spot
The bugs. They could be mealy bugs or white flies. Mites are not easy to see and they usually show stippling on the front of the leaf. Sucking pests like mealy bugs, scale, aphids usually follow the veins of the plant. While flies are more scattered and eggs are white swirls and the adults fly around when the leaves are disturbed.
Sucking pests can cause leaves to pucker and curl.
The branches turning up is because of gravity. It happens with tomatoes grown in hanging baskets too. The heavy branches are pulled down when there is nothing but air to support them but the growing tips will point up toward the light source.

Sorry for joining this late -- I'm inclined to think whitefly too. The older leaves may just be exhibiting the previously caused damage that has been expanded as the leaves grew in size, but it's possible you need to repeat treatment. Whiteflies will fly up when disturbed -- sometimes you just think you are seeing things in the corner of your eye until you learn to recognize them. But try turning over and looking under some of those leaves -- they would look like tiny white elongated flakes.
Those white patches are definitely burns from light contact. Those areas would thin and split, but dead areas can sometimes get water soaked.
