N or Mg lacking ? :(
Robertsanswered grow question 4 years ago
Purple is a sign of too cold. Nitrogen deficiency starts at bottom turning leaves yellow to top. If leaves are yellow on canopy and not rest then it is light stress. Plus .004 is really light on water. Good luck and happy growing 🌲🌲🌲👊

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 😐

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 happening

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.

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.

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.
