Too much sunlight, probably. The plant is curling inward to reduce the surface of the leaves that gets hit by sunlight. If it curls outward it's the opposite.
It could also mean a lack of water if they are curling, but I think it's a different kind. Lack of water is more like a droopy folding, while the curling as shown in OPs picture is like the leaves are rolling up
Yeah my Pilea constantly did this and other more wacky curling. I moved it further away from the sun so it got indirect light and it liked that better.
It's not new, but part of the reason she has so few leafs on the bottom. She dropped them when I transitioned her.
Fertilizer could very well be an issue, I don't really have any idea how much fertilizer my plants need and just give them a all a bit biannually (usually in the fall and spring).

Then that's the problem. You don't "fertilize" with LECA, you add the nutrients to the water every time, giving you more consistent conditions.
If you only add fertilizer from time to time, you'll get a huge amount of it instantly, too much.
Try using 1/4 strength for the darker season, and 1/2 strength in growing season to every irrigation water, and remember to flush it from time to time, around every or every second month, depending on how much it grew.
Remember to use a fertilizer that also has micronutrients, preferably one that's made for hydro. The best option would be to use a two part fertilizer with rain water.

Damn, I have both inwards and outwards curling leaves on my plant

Thanks, I'm gonna move it :D. Any Idea why it would primarily do that on the back leafs? The front should get more sunlight.
It's hard to tell from a picture, but it could still mean it's underwatered. How frequent do you water it and how much water do you give it?
Also, which direction is it facing and how close to the window is it?
