Need Advice. Wilted Leaves/Slow growth

I'm not familiar with the nutes you are using, but considering you're using r/o water, you probably need to add calmag with every feeding. I never have to use calmag because I use tap water.
Start feeding multiple times a day to run off and your problem should straighten out.
Never plain water.

I was just trying to follow cocoforcannabis nutrient schedule with just the nutes and calmg. I wasnt adding that much similar to what youre adding. Maybe those who do add it only add a tiny tiny bit. People just told me to remove it and it was good but thats just me.

I eventually quit using any charts the plants just need what they need. I clearly had lock out they said and that nutes should have enough calmg considering dtw coco.

I've never grown in coco before so take this with a grain of salt. They look like they have wet feet (overwatered) to me . I grow in rockwool and almost always have trouble navigating small plants until they grow into the blocks. The root zones of those plants are probably at best taking up a quarter of the media. You get stuck between a rock and a hard place trying to get roots ample oxygen and at the same time trying to get fresh solution to the root zone. I would say let the plants dry back a bit more so some oxygen can get to the roots. Again take this with a grain of salt. I'm really just guessing.

Edit: heres some classically overwatered youngsters in rockwool.

It's not easy to compare Coco Coir with Rockwool. RW is easily overwatered with small plants without enough roots to support enough aeration.

Coco coir on the other hand holds 22% oxygen even at full saturation. While you may see overwatering on very small seedlings it's easily sorted with some added perlite.

I've had two cycles in Rockwool and you need to be very precise with the feeding volume starting out. I remember using a pressure sprayer bottle to gauge the weight of the cubes.

Both methods grow perfectly healthy plants!

Cheers!

Plants looking that way, check your pH meter calibration too, to be safe.
