Can someone help diagnose potential problem?

First time. Outdoors in soil (not pots). One plant. This problem suddenly developed over last 2-3 days. Brown spots. Not widespread - but curious why suddenly at this late stage. Hoping to get through the next 2-3 weeks before harvesting. In northern OH. Should not be calcium deficiency problem but appears to most closely match this photos I see on the internet. Soil PH is good (around 6.5-7. Getting some Cali-mag tomorrow - opinions on if that is the correct approach. Other suggestions? Thanks, in advance.

Hey Irondon88 . You answered your own question.
You said you are 2-3 weeks to harvest. It's normal for leaves to turn colors and die, for the same reason your OH trees do in the autumn. Except trees are storing energy in their trunk. With weed, your buds are sucking what nutrients they can, in their final flowering stretch.
In a word, you're fine. Lot's of the same question going on right now. Just go with it.
