Dying leaves
I had some mild nute burn last week on a few plants. A few tips were burnt. Some lower leaves are turning yellow and dying. Is this still nute burn or something else?

Asymmetrical baby seedling
Hi everyone, just need an opinion on my poor seedling that looks a bit mutated and stressed, came home today and my timer decided to break and just stay on no matter what you press.. My heater comes on when the lights off and was 28c in there 🙄 should I move the light away?

Yellow leaves
my little GG2 is starting to lose many leaves (they turn yellow and fall even before drying) while the other is not having any problems (the only difference between the two is the "aggressiveness" used in the LST) it could be due to the flushing done (but less than 5 days ago) 🤔

Seedling light green, just want her to be happy.
Seedling is slightly yellowing. First ever hydro grow, just wondering what I should look out for. The water is ph 5.8 with fish shit, hyshield, calmag, and nutes according to seedling stage. I even added some extra plain ro water so nutes shouldn't be too strong.

Newer leaves also turning yellow at the tips. Flush?
Newer leaves also turning yellow at the tips. Started to give the plant Terra Bloom,Sugar Royal, Pure Zym and power roots again after only giving it water for 2 weeks long. Is this a nutrient burn and will a big flush help it out? Doesn't a big flush overwater the plant?

Yellow spot on my leaf. :) PH fluctuation ?
(Water change) I had set to 5.5 PH and waited 20 minutes. I put in my fertilizers, everything was fine. The next morning the ph had dropped to 4.7.. So I put it back up. The next morning yellow spots appeared on the leaves. Did you confirm that is due to ph fluctuation ? Thank's

Feuilles recourbées / problème de génétique ?
Salut les amis! 😊 J'ai un petit souci avec mes adorables feuilles de cannabis qui semblent jouer à la gymnastique. Malgré mes vérifications de température, humidité, arrosage, ph, et nutriments, le mystère persiste. Les plantes voisines adorent pourtant le même traitement.

Week Three slight leaf discoloration
In week three I'm seeing some slight discoloration. Not sure if it is something I should be concerned with. Using COCO, Worm Castings, ReCharge. Watering daily to keep the amendements active. Maybe I'm watering too much? Love to hear your thoughts. Thank you and happy growing.

Which pests do this?
Exactly what pest does this kinda damage? I have my guess, but wanna get other growers' opinion on this type of yellowing of leaves and brown spots. 6 weeks into veg. It started very early on at bottom leaves, once I trimmed them this brown spots appeared on top growth.
