Is this bud rot???

We had one day of good rain and now its sunny again. Im in so cal desert so humidity is not high. Can bud rot form with only one day of rain. The day after the storm is was 85 dergrees and back to normal desert weather. Is this bud rot or is something eatin my plant???

cmon folks, i need to know what this is.

Well, the only pic that's worth looking at is the first and its out of focus, but if you are talking about the browning tips at or near the top....yep bud rot is just starting. the spores may have already been there, and the last wave of humidity was the tipping point.

i know the pix arent that great. will have better ones up tommorow

No i dont see bud rot on that out of focus pic. Your growing sativa in the dessert doubt its budrot but a better pic is needed
