Usually a sign of over heating or lack of air movement. However, I have seen the odd plant grow like this for absolutely no reason over the last 40 years.

Looking to find out how long you need to reveg a clone Taken 2 weeks into flower. I believe it's called Monster cropping in was just curious if you had to wait for the new growth to be completely normal or could you flower it once it hits say three leaves. any info welcome thanks

Nute burn in late flower
I've encountered some late stage nute burn and have brown and twisted tips on fan leaves as well as some bronzing. I am reading different treatment options for nute burn online but what else should I try at this late stage? I flushed ph'd water w/calmag and it's slowing a bit.

What is she trying to tell me ?
Could anyone tell me why some leaves of my orange sherbet are dying ? Is it stress (the plant is in front of the fan) or cal-mag-potassium deficiency (I don’t have neither cal mag or potassium). Thanks a lot 🙏💚

Upward Curling Brown Leaves/Nutrient Lock Out?
I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light. Leaves are curling upward and browning. Not crumbling yet but look like they will be soon. Both new and old growth is being effected. Maybe the Mineralized Phosphate was too much.

Dark dots in leaves. Lamp burns?
I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

Wrinkled leaves
Why are the leaves looking so wrinkled? Do you think it might be some light issue? Genetics should be spot on, I grew a seed from the same batch and the plant was pefect
