Claw Leaf Please Help

I have a plant that is exhibiting the claw but I can't seem to identify the problem. It is growing off of ~130w of cfls with a fan constantly blowing in the room. I also checked my pH and it was around 6.5. I have been watering with a molasses mixture and also use a diluted fertilizer once a week. Any ideas what the problem is, do I need to do a flush?

i think its light stress if u ask me if it was heat they would go upward and burn at the tips of the leaf ,i have some plant do that when there trying to get as much light as they can hopefully thats yr problem other wise i think yr doing well, the only thing i see wrong is the n deff witch is normal in flower

Could it really be light stress? I also have another plant next to this one. They are both running on about 130 watts but the other looks fine only a few leaves that are close to the forming buds are curled. As for the nutes i am using miracle gro for flowering plants but only every once in a while. I use about .3 or .4 of a tsp per gallon. I water about every 4 to 5 days with a molasses mixture. Also the light i am using is strictly in the 2700k spectrum. Would it be beneficial to add a 6500k cfl?

What's the temperature like at the tops of those plants? Are these being grown inside a closet?

Yes they are in a closet. I dont have a thermometer in the room but i would say the temp is around 75 or 76 in the day and ~72 at night.

Rootbound???...check em....I had same problem and after exhausting all other options that was found to b the problem.....verrrrrrry frustrating I know.....and yes u should throw some 6500k in there...helps with the spectrum..

Hows your humidity? I've had plants look like this from a few 80%+ humidity days.

And my man.......Thats not aluminum foil you've got on the walls is it??

I don't think heat or light stress mate, your leaves look paper thin, which is usually a sign of low humidity, if heat they'd be crispy/brown on the tips,to much light =similar plus bleaching of newest growth, I think where you've got you fan is drying/ stressing your girls, check your humidity,which is often over looked, it's very important in that it helps your girls breathe properly. I hope this helps, good luck and good growing.

As food cooker says, high humidity causes similar problems too.

downward clawing IS a traditional sign of too much nutes. i would flush it good and lighten up on the nutes. once a leaf shows these signs it will stay that way so look at the new growth.

Is aluminum foil bad? I use it.

The foil could cause hotspots with strong lights. CFL are not that hot. I want to know more about your watering schedule. Sure you plants are clawing but they look def so I'm leaning towards overwatering, low ppm-ec. Did you make sure your pots were air light in between? Water with run-off each time? Have u checked the PH OF RUN OFF. ? So, what food with NPK values? How often? What size pots?
