Nutrient Burn?

My ladies are now into their 4th day of flowering, and they look like they are going to die. I had used Age Old Grow (12-6-6) on them and if i had known better i would say its nutrient burn.

Are my ladies gonna make it? How would i fix the problem?

Thank you

Also i used age old grow for the veging not the flowering...i have other nutrients for flowering but now im scared to use them lol.

cood b, how often u feedin? and dose? also how close is ur lites? temps?

i've been feeding 1/3 dose every 7-8 days. light is about a foot and a half away. and temp stays between 77-82.

i also purchased supervit which is supposed to be used for flowering, should i start using it or hold off?

You definitely have nute burn, how much light are you using? If you arent using much, the plants wont need much nutrients. Id give them 1 batch of nutrients for their whole veg, works for me unless i see otherwise
