Rust orange spotting

[burninheavy420]

Okay well first off lemme tell you that my baby is lookin great w/pistils shootin out all over the place! Recently I started to notice this spotting that is a rust orange color, it is on several of the fan leaves and i have no clue what it is. Also i was wondering what else I could feed my girl, she gets fed FF Big Bloom every other watering and i don't see any signs of over-feeding unless thats what the orange spots are :/

Would purpling stems also be a sign of a cal def?
