Untiedmymindstarted grow question 4 years ago
Noticed my leaves are starting to fold in the middle. One leaf is curling up which i know is from heat are the leaves that look like they are folding in half caused by heat as well?

Yeah they do that to decrease surface exposure, if you cant bring down the heat try increasing the humidity so the leaves dont have to sweat too hard. It looks pretty minor and fully reversable, good stuff

Siii , mucho calor :/ si no pueden aumentar la humedad del cuarto , podrías intentar con uso de intractor y extractor de aire , posicionalo justo en la parte superior junto con el panel de luz ...así el aire frío que pasa. Ayudará a bajar la Temperatura del foco l panel y saliendo enseguida por el extractor de enfrente ..obviamente esto se logra con cooltube y mangas de aluminio , otra opción es añadir un intractor de aire posicionado en la parte de abajo del armario :o

Yes, this is being caused by heat stress. The leaves are curling upwards around the edges to form a canoe-like shape which is an apparent sign of heat stress. Your temperature looks fine so I'm guessing the light is too close, try going 24" inches above the canopy instead of 18" inches, it might be too much for the plant.

She looks pretty fine for me, but leaves' colour is not even or uniform. Somewhere is dark green, and some is light.
Old leaves have some yellow spots, but I guess it was water drops' burn
I'm growing for fun btw, don't take so serious
