I have a dark devil auto seedling that has big weird splotches on it. The splotches are light/white like its being bleached.
I had a couple seedlings do this before and they recovered but i never figured out what caused it.

Sometimes when you water and some gets on the foliage, it can act like a magnifying lens in conjuction with the grow lights and burn the leaves. Questions: how often are you watering and is it town water or well water (town public water is often chlorinated), how old is she, what type of soil is she in and have you fed anything to her?

Im blanking on the brand name of soil. The name of this specific soil is groundswell, but im blanking on the brand. I water her every other day now with phed city water, thats how long it takes for her to start to feel dry. When this problem started she hadnt been watered at all since i watered while planting because she was under a dome and hadnt dried out yet. No nutrients yet except the ones in the soil.

To start, i would dial your lighting back. How high is your par? Based on you have 5 nodes in about a 1 1/2" id say your light is too strong at this point

Pardon such a late response to an old topic. I noticed that you stated you pH’d the water. Do you know what the pH of the city/town water is. If your cannabis is being grown in soil, one of the many benefits, is that soil is a great buffer of pH. Check the pH of your water to see and let me know. My well water is around 5.25 and I have a big outdoor cannabis garden and water directly with that and have no issues.
