Is this nute burn?

Hi Everyone,

Im six weeks in to flowering some of my fan leaves are turning yellow and look rusty. I was not sure if this was part of the natural flowering cycle or if this is nute burn or possibly due to the spider mite problem I had with this particular plant. Your input is apprecate.

Thanks,

No, nute burn will start at the bottom leaves. That looks like a combination of a few deficiencies. I'd give her some P & K.
