2 reasons: genetics, of course. Also phosphorus deficiency. With P deficiency, it's often caused by colder nighttime temperatures which make the plant burn through P like you'll eventually burn through the plant. Add some P and the spread will stop.

Catching a fade?Is this fade normal for a Crème de la Chem? Or is this some other kind of deficiency. This plant has not had any issues. She’s the most healthy of all of them. In the pics I’m trying to illustrate the purple color showing up on some leaves.

N tox in full swing. Lowered feeding from 1 Tsp to 3/4 Tsp Cal/Mag, and Grow/Micro from 1/2 Tsp each to 1/4 Tsp each. Hoping this helps correct. Is it possible that overwatering also contributed to excessive N uptake? I let the coco dry out a lot more (~4 days) this time.
