Interesting info, stinky.
They're actually looking healthier than ever. I re-potted earlier and the roots were absolutely not bound, they were as small and stringy as the rest of the plant, though completely white.
They've been in 10l pots for about a month, they've also been heavily flushed, the medium is 50/50 good soil and perlite.

The other plants are just fine in the exact same medium, lights, environment, etc:
