Always measure your nutes and additives carefully. Guesswork kills plants.

Likely the ph dropped too low when you od'd them with the bud enhancers. Next time they need watering, I'd flush again with properly ph'd water, then watch the new growth to see if it's happy or not.

The claw's will not change much for the better, (old leaves are old news anwway) but if all is well and returning to normal...the new growth will be the indicator. Also, I'd leave the clawed leaves alone. They look funny, but are still doing their job if pliable and green. (depending on the severity of the ph drop)
