Stop giving more nutes, they have enough crap in the soil already now plus some. Get a larger pot, go ask your local hydro, grow store for a bag of pre mixed organic soil. It will be a generic bag of what they use probably with no nutes in it "perilite, vermiculite, shredded moss and soil. Re-pot, water heavily and let her recover and use the excess nutrients it already has from the mg and schults. I'm a new grower and had similar problems trying to over feed my new plants with name brand cheap ready mixes on my first grow. While your plant is recovering, hit up the nutrient forum over the next few days and read TONS of posts for a few hours. When you find something that makes sense to you and has had proven results with other growers give that a try. Make sure you know how often your going to be watering with what nutes in what quantities BEFORE you go out and buy something.
There are guys on the nutes forum who will gladly help you, I'm just using what works for me and cant really give you any more advice on this than that. Cannabis can grow with just water and dirt so give them a break for a while until you have more confidence in your nutrient regime. They will probably perk up after a transplant into neutral soil.
PS. have you ph'd your water supply yet? Bad or over nutes with poor ph could be hitting you with a double whammy.
