what is causing the leaves to look like claws and ...

Based upon your diary, you're running light 24 hrs. at 10". I'd say to much light. A little to close. You might want to consider that 18/6 schedule, and raise your light to about 14" for awhile. Probably better off being a little to far away rather than to close. Can always lower the light if the girls start reaching. Also, I see that you really increase your light intensity during flower. That's great, but kicking out that much wattage I'd really watch my light to plant distance. Nebula, from GWE (Grow weed easy) has an excellent write up on: "Too much light vs. Too little light." I'll see if I can locate a link for you or you can just Google GWE., and that article yourself. Hope this helps. Nice work man.👍😄✌️
