Your in the beginning stages of nitrogen toxicity. The greyish dark green color on some of your leaves are an indicator. Also could be your ph not sure if u checked ph runoff, i would check that first and dont feed nitrogen see if it gets better

Looking at the pics, it seems to have pretty obvious internal pressure issues, though nutrients can affect that, but yeah...watering/humidity/oxygenation is probably related. Still looks like mainly calcium issue, but water too.

Looks like calcium (mainly) to me. I'd throw some calcium, maybe a bit of sulphur at it. Watering might in some cases exacerbate those issues (like concentrating excess nutrients, making the imbalance more apparent).

Compare leaf temperature to air temperature. Adjust your humidity and/or temperature until you see 2-4 degrees delta. That seedling needs a VPD of .5 but the full flower plant could be pushed up to 1.5. For optimal growth they need very different environments.

Nitrogen toxicity can cause calcium and potassium lockout. it looks that way. adding more calcium to feeding can help. leaf curling down is a sign of N overload.do not feed them N anymore, only bloom nutes and calcium/magnesium supplement.that plant looks like a weak genetic

Might be a little off in a micronutrient like Cal or copper. Might also want to check for thrips.

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.

Cut leavesHi, should I cut these branches at the base of the plant stem?
The plant is in the flowering stage and I think these branches can drain energy and not produce much, the other branches are already producing much more.
She's auto daiquri lime, an autoflowering strain.
Thank you!

What is wrong with these plants?I can't recognize what is happening with the two Gelato plants I have going. The lower leaves are curling down around the edges and all leaves are drooping. Can't figure out if it's over or under watering or some other issue. Any thoughts? Thanks!

Spotted crisp leavesWhat's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.
