It does look like a pretty classic nitrogen toxicity claw. If you haven’t already, cut back on the amount of nitrogen you’re feeding. Plants need a lot less nitrogen in flower as oppose to veg. I would say a flush would probably help get on the right track, but also make sure those laddies aren’t too close to the light!! Light/heat stress can cause some funky looking leaves too.

I would normally agree but it’s only the bud leafs and the plants actually slightly suffering with nitrogen deficiency so it’s definitely not that but I can see why that would be a thought

I guess my next thought if not nitrogen would be a ph issue. I have experienced some crazy twisting and cupping leaves due to ph swings.
 
What's the air circulation like in your tent? If you have a strong fan directed towards the buds with curling leaves, try turning it down, directing it elsewhere, or moving it further away. Wind burn can cause some leaves to claw while others stay normal
 
The temps are high! Like 30-32c but there’s a heatwave and nothing more I can do about that. I do think it started before the heat as well.. and the other plants are cuping slightly as expected and edges pointing up but this is the only plant with the strange twist. I have a ph soil tester and everything is in range but this is the tallest plant and closest to the fan i have on the top of the tent pointing down.. also the plant showing the least sign of classic heat stress symptoms. I will turn the fan down and see if that works. Do you think the leafs will recover or just stop spreading

One is foxtailing bad because of the heat.. not the good kind ever, it’s growing tall tails. Any way of fixing that. I was debating chopping the tops of to see it it would stop the clime and maybe fatten out instead ?

Only one way to find out lol. I’ve done it before. Splits into two just like topping a plant.
 
Hi guys, so I moved the fan and lowered the speed and then leafs have actually started to un curl so I think it done the job, so thanks to everyone’s help! As I said before that I had a nitrogen deficiency.. I fed some extra nitrogen and it fixed the problem and stoped spreading up but I have noticed all the small leafs on the bottom have not started dying on every plant … I’m having a nightmare with this grow. As you was all so helpful last time I thought I would ask your advice again.. has anyone come across anything like this

That's not the heat, that's genetics. 32C isn't high. My greenhouse is getting to 44C and my plants don't foxtail.
 
Apart from anything else, why have you left all those dead and dying leaves on the plant? If bud rot hasn't already happened, I'll be surprised. Clean them up, water with pH-adjusted water and nothing else, report back, please.
 
Well, I I think I started on the bloom nuts to early and they was suffering with nitrogen deficiency and high heat, but that problems now resolved and I put the lower death down the the already affected leafs just not recovering and dying of, also when the high heat hit the lower buds almost dried up a bit,
I just done a clear up because I had no idea that would cause bud rot, I’m not seeing any clear signs of it thank god but the lower buds are dying along with the leafs and it’s spreading up the plant.. funny thing is the tops are beautiful! Long thick coals of bud but I’m worried it going to carry on spreading up the plant
