Plant leaves curling up, brown, crunchy & more

Hi,
This will be brief because i'm heading out to class. Fed it last night and now it looks like this a day later. I had ff soil and ff nutrients. may have been heavy feeding but no more than usual. About 3 weeks old. Under t5 24w. Bad picture- camera wouldn't focus correctly. I think it might be overwatering and also nutrient burn. Any help would be great. It was a great looking plant yesterday.... really big and healthy and the nutrient water i was using didn't change from any other feeding.
Thanks

I think that plant is now deceased.. You can try to cut it all off, re-pot it in a nute free soil and water very lightly for a few weeks and see what happens..

Be careful with your feeding, baby plants dont need much..

If its an ambulance, you got a chance. In a hearse, gonna be worse.

I hope you ain't a horticulture student.

The plant was almost 4 weeks old and i normally don't add to much if any nutrients since i had the FF soil. It was taking it well for the last two weeks. I will try to rehab it but it was a free seed so i might just ditch it. anyone know what might be the cause? I have the church growing next to it and would hate for it to happen to it to.

The inner leaves are fine at the moment.

It sucks but pH can kill a plant if not done correctly.
