Some sort of claw leaf??

[Dr. D]

These are shots from my two G13 x haze they stretched alot and the very tops where this leaf problem is where above the reflector edge iv moved the light up more so i will see if they pick up

the plant is deficient down below also but now iv bumped up the feeding and it seems to be doin the job, they like there nutes...they are in coco under a 250hps il get more pics soon that sjow it in a bit better detail...thanks in advance if any got any ideas iv never seen anyhting like it bfore on my plants

hey

hey

Had a similar thing happen to a b13 x bm that i did ages ago....think it may be a genetic trait although i may well be wrong.

 

[Dr. D]

hey true that does look the same and iv seen it bfore in pics and it was always on sativas so i too thought it cud be genetic but i thought id just post up some pics to see if anyone had any ideas

i'm sure sensi's mr nice has the same looking claw leaf ,but i think its more a heat or overferting issue

 

[Growdoc]

Look like a combo of things, a bit over waterd...heat stress and possible wind burn

My 2 cents

[Dr. D]

Well its not windburn of it cud be heat stress but that is unlikley as it holds a good temp in there...over watering is the most likely cause this coco holds alot of water, iv cut down how much i water so they shud pick up...thanks

Could it possibly be an iron defeciency? I know that this problem can cause the "claw" effect.

When the plant gets hot it bends its leaves to hide the stomata and thus acheieve less transpiration. I wouldn't bump the feed level too much you have a very healthy plant and sativas condense alot of the nitrogen from the leaves. excess nitrogen in the mid flower cycle tends to cause leafyness in the bud. In your case of a sativa, extra leafy!

Genes and heat are the two primary factors in that type of leaf curl. Im guessing the curl symptom is much less pronounced on the lower half of the plant? You might get different results in the winter with the lights an extra six inches distant.

I agree, My SSH do this near the tops when they are close to the lights. I hate the way they look tho...like they're all skinny, but no harm I guess to the final product.
