That's just old N tox leafs, degradation is all buddy. But to be safe. Check underneath leafs for eggs and of course you'll see webs. Good luck pal

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.
