That is generally a symptom of heat stress, try lowering the temps if you can.

Just to confirm, this looks like nute burn, doesn't it?Burnt edges, tips curled up, canoeing. I've been having trouble balancing airflow and heat in such a small tent, and as a result the tent is on average about 28 degrees celcius daytime and the plants still get a lot of wind. Looking for whatever advice you can give! :)

Something is definitely wrong. Any tips are welcomed (be gentle lol, I’m not a professional). Nutes or lights if you had to guess? Does anyone grow organic? I’d like to learn more about that. Where do you get your seeds from? Do you like auto flowers? Tips from start to finish?TY

Leaves are fanning upwards and undergrowth is huge in flowering phase. Should i be worried about the upwards fan, should I trim on this point or just leave as is and just remove dead leaves?

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

Brown spots and yellow tips in flower, started around wk 8-9. Thanks!My 10wk old Auto Trainwreck started showing brown spots and yellow tips @ wk 8-9 but even after up'ing Calmag to each water wk 8 (1tsp/gal) it's everywhere now. It's been 75-50% the whole time- deficiency in late flower? Again big THX to the community - for more than just this.

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas. Algunos tallos están morados.

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Yellow leaves Hello, take a look at the pictures please. Leaves are turning yellow and curl. Is this a N burn, or a deficianty from some mineral? Or is this nutrient lockout? Plant does grow well!

Leaf Symptom Diagnosis The leaves (pictured with weird wrinkles and crispy edges) are showing some form of stress. Theory is that they were dehydrated from the overly salty medium, but I'd love to hear from a more experienced coco grower about if and how I should intervene to alleviate the stress.
