Leaves yellowing and falling
pepitogrillostarted grow question 5y ago
I'm starting my 4th flowering week. I'm giving them 1.8EC. The downside leaves are still falling. Some of them just drying. I'm a bit concerned right now.

During the first 3 weeks of 12/12, the plant goes into what's called the stretch, where it undergoes rapid growth; during this phase it needs a lot of nitrogen, which in this case is taking form the bottom leaves. TL/DR: it is nitrogen deficiency, give it some grow nutes.

Hi @lemonfaker it seems to me to be a nitrogen deficiency, maybe cutting down the nitrogen too early when it started flowering. But I noticed that the greener leaf in the first photo has 2 or 3 black spots, underneath it is another big but yellow leaf that also has some black spots right? if they are black spots on several leaves it may also be a deficiency of magnesium. I had the same deficiencies in a recent grow. good luck mate 👍

Is my plant showing signs of Nitrogen deficiency?Autoflower, day 40. Most leaves are in a yellowish-green tone or even completely yellow. I was mistakenly watering it with tap water, but when I noticed the yellowing, 1 week ago, I started watering with mineral water at pH 6.49.

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

Magnesium Deficiency?Is this plant suffering from Magnesium deficiency? I noticed some of the growth is yellowing and the leaves are curling upwards at the tips. The tips of the leaves is where most of the discoloration is as well.

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8

What's the problem?Hi guys, basically for the last few days the problem hasn't varied too much but I can't figure out if it's my light or if it's coming from somewhere else. Some of my leaves are curling with stains either on the leaf or like a burn on the tips.

Leafs looks bad. What's the problem?Hi.
I'm a beginner and this is my first grow on coco coir.
2 of my plants having problems.
I'm watering about every 2 days with half amount of nutrients, that the nutrient company is showing on their chart.
So i'm not sure, if it's too much nutrients or not enough nutrients.

Sénescence ou manque d'azote en phase de floraison.Les feuilles virent au jaune rapidement, se propageant aux autres. Je les ai privées d'azote pendant 10 jours en floraison, pensant que la terre enrichie suffirait. Doute entre manque d'azote et début de sénescence. Voir mon journal pour plus de détail. Merci beaucoup 🙏
