The Dreaded Claw! :o(

hey guys,

2nd grow, so still learning, having a problem with my plant at the moment, clinically curling down, looking like a claw ( so bad its almost a fist, ha ha) not funny really, this is only at the top of the plant then mybe 3 or 4 nodes down, on all fan leaves, not so much on my side/branch growth,

ive read hundreds of posts with no definative answer, some say over watering, some say too much nitrogen, some say too much heat, some say too much light, some say ph wrong,

im doing this exactly the same as my first grow, and had not 1 problem with that?

so please help!!! whats going wrong???

Are those fan leaves dark green, with burnt leaf tips? If so, it's nitrogen overfert, and the most likely cause of "the dreaded claw".lol

almost all of those could cause it. Your best bet is to start eliminating culprits. Get yourself a ph tester and check your runoff. Lift your pots and only water them when they are "light". Put your hand at the canopy level. Is it hot? If so, raise your lights or implement some temperature control (ie: cool your lights, add ac unit, fans, etc). What kind of nutrients are you using? Chemical? If so, you may need to flush the soil with water and then with a mild nutrient solution.
