Yeah My Orange Crush shows purple stems and leaf stems on the larger fans
Have heard this was a nute issue at times as well..

My OG Kush has very purple stems, but the plant is healthy and strong. Some are genetically biased towards it, and its not necessarily a problem or deficiency. Unless you have more reason to believe you have a deficiency, don't start treating a problem that might not exist, as that can create problems.
