Red Poison

Your plant is suffering from Nitrogen Toxicity. You can tell because of the dark shiny leaves along with the clawing, this actually comes from overfeeding the plant and it intakes too much nitrogen, I would suggest just giving her plain ph water no nutes until she recovers then start back with the nutrients but at a light dose. Hopefully, this was helpful and remember "Happy Growing and Free your mind one puff at a time".
