No till deficiency

The leaves on my plant have this weird ashy discoloration starting to form and I can’t diagnose it. Tried epsom salt thinking it was a Mg deficiency but no change really. Other than this plants seem fine.

That does look like a Mg deficiency to me - maybe your dose was too small, or maybe it's something else entirely - like some kind of lockout.

Good Luck!

Definitely looks like Magnesium. Try a foliar spray with Epsom for faster effect.
