Yellow part on leaf

Hey, buddy! 👋 This looks like a mutation called "two-colored leaves"! If it appears, it's usually only on one or two leaves of the plant. But it's also possible for a whole part of the plant to show something similar. Such a slight pigmentation disturbance hardly affects the plant, but it looks interesting. In biology, this phenomenon is called "sectorial chimera." To avoid confusing this mutation with some signs of nutrient deficiency, it's important to remember that a sectorial chimera only affects a few leaves of the plant. Sometimes leaves turn half purple, like with phosphorus deficiency, but if this happens only with one or two leaves on the entire plant, there's no need to worry. More often, the mutation shows up as yellow coloring! 👆 There's no reason for concern; it's not contagious to healthy plants! 👌 It's a harmless type of cannabis mutation. Good luck, buddy! ✊😇
