What are my leaves turning purple/black
Jef79answered grow question 5 years ago
Hello.. Hope u are well.. Its most likely genetics as sum pheno of gelato do have nice purple hues.. It cudb a cooler spot in ur grow space so effecting single plant bit more than others.. I noticed in pictures that ur fan leaves have brown and yellow spots wit slightly burnt tips.. This is due to slight over feed.. If its been warm the plants will drink more water than nutrient and leave ec higher than wot u put in.. Simply lower amount of nutrients uve been giving her.. They look great tho and im sure ull get a great yeild of quality buds.. Gud luck n stay safe.. 👍

BTW It may be more helpful/easier to diagnose if you took pics under white light

Looks like it could just be genetics, but be careful because it does look similar to a phosphorus deficiency if it starts on older leaves first. Some of the others in the background look to have a calcium deficiency.

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.

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.

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
