What size container is it in? Can't see it relative to plant size. Also, how long has it been in current container? I believe clawing leaves like that in flower can indicate a N deficiency. Just guessing that it's in too small of a container, possibly rootbound as well, could be throwing pH all out of whack. I'm sure there's still a troubleshooting form somewhere around here, should probably fill that so the experts can give you solid advice. No info makes everything a guess.
