Hey LC, what type of nutrients are you using, and how much? What does the nutrient package say to give them?

The "claw" is caused by too much nitrogen. You should be giving them much less nitrogen during flowering. Usually, a nutrient that is preformulated for flowering is used at the amounts suggested on the package.
