It look more like phosphorus deficiency to me. They are more purple-ish than rust colored imho, but yes, more info would help. Can you fill out a help ticket and post a pic of the overall plant?

We’ll need pics of the whole plant, as well as that support ticket. Any chance to get pics taken under better lighting?
