A movie that briefly and implausibly takes place where I'm from.

Has our history department been infiltrated by geographers or something? Because this is not convincing me a history A-level is a good option if I want my career to proceed beyond 'assistant'.

Q: do these leaves have "yellow or purple tints" (=potassium deficiency: give potassium) or are they "yellowing with reddish brown tints" (=magnesium deficiency: soil has too much potassium)?

I am confident it is an unhappy plant needing either more or less potassium.
