Yellow and pale leaves of plants. Purple stems.
The week before flowering, I flushed the pots and brought the tds to 700ppm. Don't you think the leaves are dull? I feel there is a problem??

Leaf Yellowing?
What is the yellowing in the last pic? The soil is top 20% Atami Cocos, bottom 80% store bought organic super soil. Watering tap water (EC 0.284/142 ppm), pH'd down from 7.9 to 6.5 with citric acid... I think that's probably the problem? Any advice for the high pH tap water?

Yellow leaves - Sohum living soil
Have been growing these in sohum living soil - they are nearly 9 weeks old - they look great but there are many yellowing leaves - would a small dose of blooming nutrient help at this stage? or is all normal and should just use water as normal til the end? thanks!

Yellow/ brown leaves #2 (pics didn’t post the 1st time)
Hey guys so my plants are starting to turn this yellowish color and I’m not sure what the problem could be. Sorry for the second pic, it’s kinda blurry but that’s the actual color compared to the other leaves. It’s my first grow and I’m kinda lost on a solution . Many thanks

Hi everyone.. The leaves that are turning yellow, could it be due to over-fertilization? Or excess nitrogen?

Bud leaves turning yellow ? End ? Burned ?

Any ideas what this could be?
Out of all 6, she’s the only one acting up. Transplanted her last sunday. Started seeing this around Tuesday. I do believe I overwatered on accident but all of my other girls are healthy. I’ve done nothing different between them

Brown/rust spots and yellow leaves at the bottom
Plant in late veg (soil) is showing spreading brown/rust spots on upper leaves and rapid yellowing on lower leaves. Frist only at one plant and now at the others too. I suspect a pH-induced Cal-Mag lockout. But I always check pH to be around 6,5. What should I do?

Leaf discolouration. Nutrient deficiency?
Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?
