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 🙏

Fan Leaf tips and light spotting
Been feeding ferts regularly every third day watering. Using BioThrive Grow, Bloom & CalMag. Seeing some leaf tips burning and light yellowish spots. Overall the plant looks healthy, there are only 5-6 leaves showing these signs. What is wrong with my G ?

Light colored sugar leaves
I'm at the end of week 6 and the plant is looking healthy overall but there are some bud sites that have some sugar leaves that are developing with a lime green color. Im thinking I might have been a little high on the ec so I backed off a couple days ago. Thoughts?

Rate the Bud - 6 Week completed flowering
So this is my first time growing with using BioThrive grow, bloom, calmag bottle ferts. Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning. On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?

Cut off yellow leaves.
Can I cut off these leaves? I am worried that this is an autoflowering plant and it will be an additional stress for it. But it also seems to me that it is spending some effort to keep these leaves alive and it would be better if it spent this effort on the buds.

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

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.

After looking at some pictures and reverse image searching some of the attached pictures. I think it maybe both phosphorus and potassium deficiency.

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?
