Nute burn?! help!

My plant's leaves are wilting and crumbling, mostly just the large fan leaves. I'm in the third week of flowering. I think its nute burn. I read somewhere that I should soak it in water for a day and then re-pot. Is this what I should do or should i just cut back on the nutes? Should I remove the fan leaves?

some pictures would be good,if it is nute burn just flush by watering ya plant with 3 times the pot capacity.some ppl just stop giving there plant nutes for a while.make sure the ph is fine before you water.

thanks skitz will do
