it may just be natural death, they do that before harvesting, but since its so early, I doubt it. dont give nutes. sounds like a burn, and whats the heat?

[Garden Knowm]

WHich way are the leaves curling...? up or down?

[ilovebongs]

leaves are curling upwards, and the heat is 87 degreesf-27 degrees celcious.most of the other leaves, are dark green-normal as they have always been.its 99% of the bigger leaves that have it, none of the others do.

oh yeah the light is 2 ft away from the plants, and i cant feel the heat when i put my hand at the top of the plants

[BobBong]

lower leaves?

did you increase the light at some point?

[ilovebongs]

it started off being the lower leaves but it has gradually spread to the top.top leaves are not so bad.appart from the leaves being bad they are growing well, buds are getting fatter everyday, and it is growing taller

[AdidasZ21]

Might just not be getting enough light.

[mellow mood]

i doubt it. pretty strange. how often do u water? is the heat just correct or u think u couls approach more the light? what ferts do u use and how often? pics would help but sorry i really cant see something else than fert, heat or water problem. check the ph, maybe its too low or high. should be around neutral(7.0), or like 6.7. good luck man

[ilovebongs]

they get watered when the soil is going dry, like i should.i will post a picture of one of the leaves later, we have now trimmed of the bad leaves but i dont want it spreading.
