Is this bad?

I have a beautiful outdoor female plant about 8 weeks into flowering I found her growing randomly one day must have dropped a seed but she is is truly a gift.
Everything has been great until this morning after a night of rain I had to cover her but today I noticed my leaves are looking a bit dark and a few of the flowers pistils look
a bit funny. I haven't been giving her any nutrients just water only. Could this be bud rot?? Any help is greatly appreciated.

I'm no expert I am a beginner grower myself but if I had to guess I would say this is either a case of a PH problem, over watering, or there is some kind of deficiency in your grow. If you live in an area that could have had some acid rain it would have raised the PH too high possibly. The drooping leaves could indicate over watering from the night of rain, it is also possible your leaves are getting this yellowish color from a deficiency which I do not know anything about but you can find articles online about specific deficiencies.

Naaa not bud rot. Just got a bit overwatered during the rain. Make sure when there is morning dew or water sitting on the plant to knock it off before the sun hits it as it acts like a magnifying glass and burns the plant. This is most likely the case here. New flowers are very fragile...they are burnt but will repair. Let it dry out well before watering

It should survive. Some sort of bloom food should really help it.

Okay great information from everyone appreciate the replies. I'm gonna get some bloom food, thanks for the help!
