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.

Slight yellowing of fan leavesYellowing of leaves on my second grow. Only 1 of 3 plants doing it. Same medium, same light, same watering etc. Only used a general 1/1/1 feed so far and water. Read about nutrient deficiency, over/under watering etc but I'm baffled. No adverse effects otherwiseWeek 7

Jaunissement, excès ou carence ?Ma Amnesia présente une décoloration rapide des feuilles en jaunes.
Je pensais qu'elle avait un excès car les pointes brûlait
J'ai effectué un rinçage et mis une alimentation douce pour repartir mais le problème s'est aggravé et a accélérer le jaunissement.
Merci d'avance ! 🌱Week 10

Any ideas to what might be causing these leaves to yellow/die? Only reasons I can think of are nutrient lockout, having the lights too close (although I've heard with CFLs theres pretty much no such thing as too close) or possible having the heater running, or constant fan airWeek 3

Why going yellow from inside to outsidePot leaves turning yellow slowly from the inside and stems lowering in green colour im thinking most likely alittle over nutting along with over watering would like to avoid flushing if possible rh has been a little low but not significantly so ph 6.4-6.6 runoff 6.0-5.8Leaves.

Seedling adviceHi, my light was at 60cm with an average humidity of 70 degrees Celsius. There’s slight dryness around the tips, yellowing, crispness. Remedy thus far: I moved the light up to about 75 cm, it’s a 100W led. Humidity also dropped to about 60 degrees. Any advice to remedy?Leaves. Color - Yellow

Lime green/yellow plantsOk so my OG Ladies are looking pretty lime green/yellow.
I noticed when I mixed my nutes I think I mixed up the a and b bottles I also don’t really check PH, relying on microbes to buffer. I checked it and it’s high. Iv fixed the res mix and upped the dose. It’s been 24h ish…Week 8
