Yeah buddy, i think that you overstressed.
The left one I don't think will get better but hope so, the other 2 you will find out in a week.
What you can do is level up this light, it looks like a good and strong one and veery close to the plants.
Be patience with the light and also the fed, give them time, space and water, maybe they'll recover nicely!
Happy growing friend!
