I did have a soil test done and added appropriate amendments to correct nitrogen and potassium (the two I was most low in) so I don’t think I’m deficient (I also don’t think I overdid it as I was careful not to add too much) but I was really high in phosphorus if that helps. Any advice is welcome! Thanks!   Tuesday, June 6 View Page Does anyone know what might be causing this type of yellowing on my leaves? I performed a soil test and was really high in phosphorus, zinc, and iron but I don't know if it could produce this type of discoloration. Any information is welcome.
