rust colored stems

[slowmo77]

ok, ive had purple stems, green, and now a rusty color. i've learned that the purple is from the strain i was growing could i assume the same about the rusty colored ones aswell. i've noticed that unlike the purple these are showing the same color in the center veins of the leafs. not the small veins but the main down the middle. i just wanna make sure its not a deffi, of some kind they're about 4 weeks into flowering but they've been this color since about 4 weeks of growth. any ideas? i would post pics but cam won't take pics clear enough to see

[thc is good for me]

ive noticed stems turn purple after they are done growing fast all new growth on my plants is green and oldgrowth is purple.

the purple i've seen several times.it doesn't worry me its this rusty color im getting. its only one plant doing it the rest are fine. i guess its the same as the purple. oh well it looks healthy so i guess i won't worry about untill its a problem.
