what size container are they in? How is the drainage? The plant looks like some N deficiency, with some of the older fan leaves turning yellow without chlorosis showing. This could also be due to the plant out growing her pot... but more info would be great in that aspect.
thanks
I guess the part of me that assumes there's proper normal watering/draining/etc needs to be toggled off.. as my statements up the page were assuming everything to be proper, with a few provisos relating to pH and other things that could affect what we're seeing.

The OP is using coco, so I am at a loss on what watering/drainage is needed... The soil looked wet, though could be right after watering, so I asked about this. I will bow out as I am not a coco grower, though I still believe that you have to make sure there is enough root room... bah sorry OP, non coco grower. Please take that into consideration.

Ive read about alot of problems with leaves but cant quite put my finger on whats causing this "claw" like leaf. I have a few of them on my plants but not all of them. Mainly on the bigger leaves and fan leaves can someone help me with this please and help with correcting the problem as im 2 weeks away from flower.

By the look of the whole leaf turning down instead of the tip, I'd say over water, but like everyone else, we need a good pic...it could be N...it could be it needs fed...could be a toxicity prob...could be a good pic...lmao Jokn man

Have you checked the pH and EC of your runoff when watering. Some brands of coco can have high salt content.
Good tip, this is something else I would have assumed was done.. being the rinsing of the coco a few times w/pH'd water (or hot water, as some do to help dissolve the salts) and a light mix of cal/mag (extremely light) pre-settling into their new home.

Wats your humidity in it grow enviroment? I have this problem in the winter when my humidity drops below 30%. I also grow in coco.

Humidity requirements vary depending on clone/veg/flower.. perhaps we should specify what phase is being discussed so there's not mis-communication?

6th week of veg. The plants seem okay. Apart from this minor issue. I ph my water at 5.8 and run offs at 5.7 ppm is around 600-700. I feed them 2ml of sensigrow a+b to the Litre and 2L a day. I recently watered them with 4l bcz i wated 2.5 l and they was no run off so gave them an extra bit till i got 20% run off. The strain is kali kush. A fairly hardy strain, short and bushy. I have noticed a bit of nute burn on the new growth so im going to back off the nutes slightly for the next few days and ween the bitch up.

How dry do your pots get between waterings? What size Pots are you in? I grow in 2 gal pots of coco and flower when they get 14" tall and find that after the first week of flowering i have to water at least twice a day. Try watering them and check on them an hour later and see if there is any improvement.
