This purple coloring is from a substance called Anthocyanin. It is harmless and is produced by the plant itself when it needs to protect itself a little from environmental factors such as strong sun or cold nights.
Most cannabis plants produce anthocyanin near the end of their lives regardless - - especially when subject to cold-ish temperatures - - and as such is not a sign of anything else but age in your case.

hey there, the colorful splotches are actually a potassium sign , i guess this beast is just really hungry for K which is very much used in flower and resin production. Looks like it's quite late in the game, so i dont really recommend changing anything, just proceed with you flush and enjoy the colors. Hope this helps ! 🚀

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared.
Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

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.

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Brown spots on leaves! To Flush or not to Flush? That is the Question.Hello,
Seeing lots of brown spots developing around middle tier leaves. Reddit is telling me I should flush with 15 gallons of water to get rid of salts around the roots. That seems extreme but if that’s the cure I’d like to know more and can I use my tap water (7.1pH 133ppm)?
