Untiedmymindstarted grow question 4y 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.

Weird looking seedlings? (uploaded vid)My seedlings, especially Seedling 1, look kinda weird to me. Seedling 1 appears to have some weird yellow spots here and there and the leaves look cut? They just look really weird and not like normal cannabis leaves, both seedlings have their leaves going up at the corners.

Leaf discoloration There is a purple/blue tint to the tips of my older leaves. New growth coming in lighter green. Slightly red and purples stems only at base of oldest leaves. Leaves also taco curling slightly. Thinking phosphorous deficiency at this point, maybe combination N toxicity and heat?

Brown marks on leaves and drooping, sad plant Some issues developing with the FCxForum strain, some brown markings on the leaves, no signs of this on the DeezNugs. I know the pics aren't great but anyone have any idea what they could be? I'm starting to think they are water splashes but one of the FC is drooping quite a lot.

White developing on leaves Hi all. Very much a newbie question so apologies for poor knowledge. Just stared 4th week of flower and opened the tent to see the leaves on one of the plants developing white hairs. Is this ok? Or something to be concerned about? Many thanks. 👍

Trimming during flower Flipping from veg to flower, how much should I trim the fan leaves around the bud sites, how much should I trim as the buds grow? Do these fan leaves become bud and stems? When should I stop trimming completely? Thank you.

Anyone have any ideas what this orange/brown mark could be? She’s in RQS easy boost and only been getting ph 6 water. I changed her pot yesterday, possibly something to do with that? Maybe different ph in new medium? Only one affected so far out of 3 plants. Thanks!
