Rust colored streaks on fan leaf

  1. hey everybody...been flowering under a 1000 w hps for a week. Using FoxFarm Ocean potting soil...things have been going swimmingly until I noticed these rust colored spots (and streaks) on a couple of fan leaves. Just popped up over the past 2 days. I don't think it's a problem with the light...wondering if it's a nutrient deficency. Any ideas of what to check? Ways to correct it? The plants still look healthy except for the streaks...
