Well, TBH I wouldn't be too concerned about the first two pics, but the third looks a bit like me i.e. seen better days. I think this has resulted from a dry atmosphere.....try mist spraying on warm days.
Epsom salts (sulphate of magnesium) is to balance a magnesium deficiency.....which is what I think yours doesn't have.
Yellow leaves are a sign of magnesium deficiency.
Bet Monty Don don't know that!
