they didn't look hungry to me, no matter what your schedule maybe; you cant just feed them because its time.
the plant on the left, its big enough that the lowest 5's could loose color IMHO without much concern.
now; your locked out, toxic, and maybe over watered. that's three weeks in rehab.
pots are too small, too shinny, your carpet is awful, and your PS controller looks like a hurricane survivor from a helicopter.
you could flush them, but it would get worse before it got better.
maybe move them to bigger pots, shake as much soil off the root ball and water it in new medium.
