Imo, seedlings like it a little warmer and little more humid than your ranges. Like your top ends would be bottom end. temps 75-85 and humidity 60-80. That said, seems like you’re close enough. Might be the coco. I just know how I do it. Floating on in shot glass till taproot like an inch. Into rapid rooters into first set decently established. Then into solo cup or final pot. I water daily once in coco and quickly transition to multi day feedings. Minimal light until a Around two weeks old. T5, cfls, or if primary light, pretty far away. Then I’ll start turning light up or lowering (for lights with no dimmer). Good luck!

Light stress.. pull them way back . With coco you water when 50% dry for now on

I've found what the issue was it was the cheep 10 pound coco I was using it add charge in it so I got new coco washed the roots put them in new coco them give them a weak feed added a bit of calmag and ph to 5.8 they seen to be growing again thanks for all the comments and I hope this helps anyone else who as the same issue

I think there limp because there not getting enough light 25% is low but not sure what light you have especially if you don't have a tent also 33 inches without a tent is high.
I run my 2000 mars light at 75% 20 inches above.
First 10 days you should be running 70 to 80% humidity then slowly taper down until flower of 40%
Good luck take a look at my diary I'm in the same boat..

He figured out it was the coco that wasn’t buffered.

I got told this from a guy who as done loads of grows with the mars hydro 2000 i got the same light to ""i run mine at 25% light at 30 inches in seedling stage then I bump it up to 50% light at 22 to 24 inches in veg then I slowly tern it up in the first 4 week of flower to 100% at 20 inches week 5 I bring it down to 17 inches till the end of the grow"""I followed that on my last one and was fine worked well
