Why are my plants leaves so bright green/yellow?
OrganicCannabisConnoisseurstarted grow question 4 years ago
Wondering if anyone knows why the plants might be looking as light green as they are? We are running a purely organic grow and have not added nutrients beyond the super soil mixture. Wondering if anyone has any tips or suggestions, thanks!

I'll be honest and say they look healthy to me. A picture under natural light may have given a better idea. Purple lights tend to hide problems in pictures. If you feel their colour is a little light,she is probably hungry. Happy growing ✌️

Too much P and K seems most likely as the top growth looks mostly affected.

It could be several things. First, it might be nothing-it's hard for me to see from the pic, but new growth is often light green. Second, have you changed your lighting at all? Moving a light closer or installing a higher intensity light could be giving them some light burn, this commonly affects the leaves closest to the light first. Lastly, it could be a cal/mag issue. I would try giving them a dose of calmag and see if they begin to improve. You could also make a foliar spray of epsom salts to see if it is just magnesium causing it. Good luck!!

Blätter gelb und fallen ab Blütewoche 9Aktuell machen mir meine Pflanzen echt Sorgen, viele Blätter werden sehr schnell gelb und fallen von allein ab obwohl ich bei jedem gießen Dünge. Sollte ich noch mehr düngen und häufiger gießen? Die Buds sehen soweit gut aus nur sind bis jetzt immernoch mehr weiße Haare als Blüte

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own.
I’m not sure if it’s a nutrient deficiency or blockout from ph or something else.
I watered them only with water ph 6.5.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flowerThe odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.
