Trouble with a seedling. HELPPPPP!!

I have no idea what’s wrong with this plant. I started with two clones and there doing great but I tried my hand at a seed and it’s been a struggle. It’s been in The same happy frog soil for a few weeks now and it just has been getting worse. I haven’t feed it any nutes. The light is 250 led and it’s 25 inches away. The temp has fluxes from 93 to 63. The leaves are inward and it seems to be burned. Help!!!

Looks dry to me, although it also looks like you've been feeding it nutrients. Give it plenty of plain water and see how she responds! Good luck Bro!

I would wait until the next watering and flush them thoroughly. Wait a few days and watch...

In the pics, I only see old tips burning. To me this indicates it's just putting more energy into the new growth and letting the first set die.
