That does look weird. I'd second re-calibrating your meters... As for less is more.. it's always best to start out weak until your plants tell you otherwise. You can fix def far easier than tox.. well no.. that's not true, you can fix them both easily, but the tox will do more dmg. That said, I'm currently running my flower room res at 1200
How often are you feeding them? What were they in before you potted them up? Did they just come straight out of a humidity dome into the open air?
The one in the background actually looks deficient but if they are in shock from a change in temp and humidity, that might explain it. The potting on itself shouldn't cause them such pain.
Looking at the other pics, it kinda looks like Mag def. Check those meters, make sure you're not running low.
