Seedling is dying! Help please!

Good day there. On august 30th I planted some seeds. Only one of those seeds sprouted. Everything went well until yesterday.. the seedling started to bend so I made a support for it. Today it looks as if it going to die.

This is my setup:

Location: Central America 850 Meters above sea level.
Pots: Pete Moss mini pots
Soil: Schultz Potting soil
Water: Rain water that I have been collecting

(I have been watering it 2 times a day with a sprayer)


Once the seedling sprouted I have taken out to the sun from 10am to 4pm

What have I done here? Can anyone help me please? Can I save the plant?
I'm a noob so please help!

Here are the pictures:
