Sieht wie beginnender Stickstoffmangel aus. Eine gute Gabe Stickstoff ist jetzt notwendig. Beobachte, ob die jüngeren Blätter auch langsam heller werden. Und falls möglich, gerne auch den pH-Wert checken, evtl. kommt das Problem daher.

Yellow bright new growth
New leaves on the Candy Kush plant #1 are bright green/yellow. This seems to have started when increased biogrow from 2ml/l to 3ml/l. Iron, zinc or sulphur deficiency? Only give calmag on next feed? Might have measured pH before adding nutrients so Faber wrong pH?

Starting to fade? Or nutrient deficiency?
One of my plants has several fan leaves that are turning yellow/purple, and I can't tell if it's low on N or starting to fade. The plants are 2 days into week 5 of flower with a 9-10 week flower period, so it seems a little early for it to be turning colors like this.

Leaves turning yellow
Old leaves die,mig-age turn light green,new stay green.Is this normal for just week 4 of flowering on my auto? Do you think it might be ready sooner than week 11? Or is it just a problem? "feeding/watering every 4 days,never used cal/mag supply,medium=soil light" Thanks growers

Day 40, I recently discovered my ph meter was faulty and my soil ph is high 7.3. I’m going to do a flush today with just water 6.5ph. I’m using living soil. What do you think will this be good for them? How do they look? My data shows me a daily average of 80.5F and 58% RH.

Magnesium or Nutrient Burn or?
Magnesium deficiency, or nutrient burn or??? Only on the lower leaves so far, curling down was existing genetics - but the burnt tips are new and some have even curled up now. Probably 5+ weeks left so too early for natural dying off?

4 days without water
I had to leave for 4 days this past week. Gave both plants H2O before leaving but I came back and one of my plants has some ugly yellow and brown leaves. Do I need to do anything to correct this or just get back to my routine feedings?

Flush or what to do ?
Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?

Seedlings yellowing and curled
2 out of 9 plants are looking weird. 1 has yellow appearing and the other seems to be curled. My pH tester has stopped working so ive been using drinking water until I get a new meter. Do you think its a pH problem? Just seems strange that it's only 2 out of 9
