Not the cavalry, but yes drink drink drink....
No nutes. If you've got organic soil, there's more than enough there for this sized plant.
You said over watering, but the top of the pots don't look like that.
You have a mix of perlite and soil, ok, just checking for drainage like rocks in the bottom of the pot?
Dampening the top of the soil....ok this is underwatering. The entire media should be wet. And not just around the plant...mobilise the nutrients in the soil to the roots by watering....especially if they've eaten everything within range of the roots.
If you're worried about movement of soil when watering...hydrtoton balls, inch layer of sand or decorative pebbles...take your pick...that way you'll be able to water away, without worry about floating it all outta the pot.
Any deficiencies visable just may because if the roots aren't getting water and nutrients moved into contact with them, they're never gunna get em if the soil is dry.
Humidity I'd be tempted to bring down, but considering their condition, not until they're better.
My 2c give them a good drink first with PH water at room temp. Observe changes say at 2, 12, and 24 hours.
