Dying fan leaves

[guitartom]

I have two girls of unknown origin. Just started week six of flowering. Last week, the fan leaves started dying. I see no apparent pests, ph is about 6-6.5 in a soil grow. I have tried to attach pics but no luck yet. Leaves are yellow with brown spots or blotches. BTW, the trichomes are still pretty clear. Any ideas?

Tried spraying Uncle Jack's dead bug brew for the few thrips around. Checked ph again in reservoir (6.5) and added tiger bloom to it for possible nute deficiencies . Using auto pot watering system. Plenty of solution available to plants. I am now freaking out as the dying leaves have spread to the buds. Too early to harvest but I don't want to lose all. All ideas welcome.
