Sudden Leaf Yellowing – Lighting Issue or Something Else?
Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.

Verfärbte Blätter
Verfärbte und teilweise vertrocknete Blätter bei meiner Autoflower in Woche 9. Nährstoffmangel, Nährstoffüberschuss, zu viel Licht? Grobe mit biobizz biogrow, biobloom und topmax. Woran könnte es liegen?

Upper leaves are yellow and not smooth
I noticed leaves on top are closing and today are yellowish. Older plant aren’t stretching more, I thought it’s too much light or too hot but it’s kinda weird because light are at 40cm from longer plant and 50 from smaller, temperature are max 26C. So, it’s normal?

Stickstoffmangel?
Könnte das ein Zeichen für einen Stickstoffmangel sein? Diese verfärbungen kann ich momentan bei beiden Purplematics beobachten.

Help with deficiency
What kind of deficiency i am facing here? The plant is Royal Jack auto in his 6th week from seed. I have been feeding nutrients from BioBizz based on 1/4 of their given scheme. Watering with 3L whenever the pot feels light (every 2-3 days)

Hi there, 2 plants of bluedream auto. One of them 18days and the other one 22days old. There are some yellow marks on the leaves. Can you help me? Is there N or Mg deficiency or another problem? I watered yesterday when the lights turned off. Thanks.

Week 2: One of the plants still doesn't look good + other beginner questions :)
Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

Bottom leaves yellowish - why? And can I top?
On both of my plants (C99 & S.A.D.) the bottom leaves are turning yellowish and I can't figure out why. I'd also like to top them this week (above 3rd node), but I'm hesitant because of the leaves. Any advice on what they may be missing, and whether I should wait with topping?

Nitrogen deficit?
The bigger plant is struggeling a bit again. After some talks and readings it could be a nitrogen deficit but am not really sure how if I should react to it, since the need of the plant should get less for nitrogen in the next weeks. Please read my journal for more information.
