I feed them organic nutrients, following the chart that was provided by BioBizz. Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear.

I have no idea what these brown spots are on my seedling?Brown/ rusty looking spots on seedling. Only thing I did was spray with a Epson salt and B52 foliar spray. The soil is deprived of magnesium so that’s why. I think I corrected by using cal mag. The sister plant is a few weeks ahead and showing recovery.
