I’m at a lose this is my first grow and I’m doing the exact same thing to both plants and I’m using ocean forest potting soil with nothing added and it looks like one of my plants are dying from nutrient burn and the other is super healthy... help! I wanna save my critical purple and idk what to do. Here’s a pic of both.

Looks like there is several issues. Can you give is some more info? What is the pH and PPM of the soil runoff? What grow light are you using and how far is it away from the plant?
