There's no visible Thrip damage on those plants. I could see it easily, it looks like mini drunk drivers painted white curlicues on your leafs.
Your picture could be of a thrip, gnat or flying aphid. There's just so many species of each, and I'm not sure what kinda bugs you get in S.A.
Not to freak you out, but since we're already at Defc0n-1, that might be a phylloxera, a flying root aphid. It fists (I'm leaving it!) your scenario too. Low root mass, no other issues, and they perked up after treatment.
I am totally NOT sure of any of this, but give this a look, and keep treating as mildly as you can for root/leaf based pests.
Since root development is also low, the medium might have had something in it out of whack. Might be worth it to uppot just in case, shake a bit off, and then fill with less perlite, more coco? If you're in 5s cut them off and go 7s...bump em up a size. I say this because the leaf damage doesn't look necessarily like pests, it is almost too uniform.
Here's some pics I stole under fair use.... farking IP attys lol.
Check to see if those are brown spots on your roots (could be coco bits), where these guys might be munching. As you can see, just this one species (grape phylloxera), has several different shapes and sizes ... fucking flying borg.
Great to see them look better, a sight for sore eyes. You're on the right track of action my friend, positive vibes.
