I would definitely back off the nutrients for a week or 2 at least,when the tips of every leaf are burnt and the bottom leaves are curling and crispy like that that's a serious case of toxicity, I have never heard of the nutes your using if I was you I would look into NPK raw or Lotus nutrients. You may be able to bring her back but I have never seen this bad toxicity during veg so I couldn't say with 100% certainty, it could be a lockout issue honestly ,when you feed too much of 1 nutrient it will lock out others not allowing the plant to uptake all the essential micro and macro nutrients it needs to flourish,not trying to be a dick either im just trying to help you for future grows
