Leaves getting darker
herbalistsswordstarted grow question 4 years ago
Noticed the leaves are turning a shade of purple. Is this normal or some nutrient issue?

Justa_Retardanswered grow question 4 years ago
Doesn't look normal for the strain you're growing, so it's probably because of cold nights.. cold can make the plant switch out the chlorophyll for Anthocyanins..
- It's not really a bad thing, as it makes your plant capable of absorbing a larger spectrum from the sun, tho at a diminished capacity.

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.8 months ago

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.Leaves. Color - Dark-purple

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.Leaves.

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.Week 10

Dark purple areas on leaves — genes or environment/feeding problem?What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors?
I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐a month ago

Brown/yellow/purple leaves inThis started out as brown spots on big fan leaves and has turned into what you see on the pictures. I've been ignoring the discoloration until I was greeted by some wilted, dead leaves on plant #2 today.
I'm not worried at this point, just really want to know what's happeninga month ago
