that looks like residue from water/feeding as there is similar stuff on the edge of the pot

Ya it just looks like water sat on the leaves to long the plant will naturally let that leaf die when its almost all dead cut it off. The plant can use the nutrients in the leaf so you can leave it on for now if you want.
