This seedling was doing fine but I came back a few hours later and colors started getting worse and a hole in the leaf appeared somehow. These are my other plants that went through a similar start but not as bad but they seem to have fully recovered. This is my first grow, any and all help is appreciated.

Guessing the correct plant ailment is difficult. To me it looks like over-feeding. Seedlings can't handle much fertilizer, but even then they can struggle, and recover from too much food when they get bigger and can use it. The blurple light makes color assessment difficult, but downward clawing, too-green leaves are signs of overfeeding. There could also be bad water or wrong pH issues that can have unexpected consequences. Some soils have fertilizer in them already, and might not be suitable for seeds.
