not sure if i should trash these to prevent spreading.

viens are purple im pretty sure due to my light setup. but i noticed these 7pot douglahs have some brown spots on leaves.

any ideas or suggestions

if i remember right it's from the Light ... make the plant produce a beepload of anthocyanin pigments

plant produce that effect to protect the leaves like when you get a tan while expose to sun... but it's not a sunburn...
it will replace itself... dont worry

WIKI
anthocyanin pigment : anthocyanins have been shown to act as a "sunscreen", protecting cells from high-light damage by absorbing blue-green and ultraviolet light, thereby protecting the tissues from photoinhibition, or high-light stress

do you think im pretty safe saying this is from "sunburn" or does this look like a fungal issue?
