Why is my Ice Wreck Seedling browning? It is 2 feet from the light, in the same tent as 6 other plants and is the only one looking this way. 6.5 pH, planted in super soil, watered when soil is dry.

I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad

Would Epsom salt be helpful for these brown spots? If so, how many ppm? Is it OK to reduce pH with citric acid and distilled water in nute mix?

Thankfully not my plant but what do you think this deficiency is? My first thought was actually that one plant fungus r something that causes brown circle like spots. This is the top of the plant. No curling to leaves.
