Hard to tell with the picture. Looks like a small pot—- transplant. Sometimes it can be genetics, light burn, etx—- not enough to go on here

The flowered one seems to be under a viral attack, maybe substrate too wet. The small one....seems it has undergone some sort of stress. Maybe heat, or been sprayed in full sun or under powerful lights.

Purpling, contorting, drying, yellowing.
Leaves are going all nuts, i think it was from a bad feeding, i've been too busy, no time for notes, they started going purple after feeding so i used plain water for the next 3 waterings with +water, tops started showing calcium lack, anyone can confirm? Give bloom+cal right?thx

Нлвые проблемы с переводом на цветение
Заметил побеление на кончиках листьев. В основном на нижних, но есть и на паре верхних. Не могу определить, то ли перекормил, добавив Bloom booster, то ли дефицит калия и кальция с переводом на цветение, буду рад любым советам и адекватной критике

What are some of the telltale signs that a plant needs more nutrients? Not an immediate issue but just wanted to know for future reference. Thanks in advance 😁👍

Your opinion?
Today flushing the wedding cake i was thinking that the problem was an excess of nutrients, but instead water was quite clean, around 1100ppm at the first drain, after several flushes water is now on 600ppm. I also raised the lights.. I still do not understand 🤔

Yellow and burnt leaves
Yellow on one side and pretty much green on the other. Why? Lol I'm light on the nutes. I dont think I've been giving to much. Maybe not enough? I hope it makes it.

Yellow Colour
Some leaves have been turning yellow. Especially the lower ones. I thought it was a nitrogen deficiency as I didn't give the plant any nutrients till 2 weeks ago. Now I am feeding her with Biobizz nutrients according to their table. Should I be worried? Any recommendations?

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 🙏

BT21 Probleme?
Hallo liebe Grower, bei mir ist BT 21. Kann mir jemand sagen warum die Blätter der Blütenstände so „Neongrün“ werden ? Liegt es an Nährstoffen oder zu viel Beleuchtung? Die Lampe ist recht nah dran da keine Luft mehr nach oben ist Wäre super wenn jemand einen Tipp für mich hätte

Lockout??
I’m growing in promix. I foolishly wasn’t checking my runoff. I checked last feed and it was 3600EC. Is that why leaves are going light green/ yellow. I never saw signs of burning (leaf tips turning up)

Denkt ihr die plötzliche gelb Färbung der oberen Blätter kommt durch die Blüte oder weist das eher auf einen Mangel hin?
