First year growing Marijuana. Many years of growing vegetables.
My first plant was doing well until I left for a 2 week trip in the middle of September. I returned to see many leaves turning brown. Since there was a big heat wave while I was gone I thought it was just underwatered. Here is a picture from that time:
I watered a lot over the next two weeks but entire sections of the plant turned entirely brown and brittle. Other parts of the plant look totally fine.
Here are photos from today.
Good part of plant:
bad part of plant:
Can someone help identifying the problem? Thanks so much!

Since you are flowering it’s rough
I would say remove leaves and have new ones grow but…
I guess remove them anyways to let light in to lower branches. I’d also wait for others who have experience with this to answer
Under watering would affect the whole plant. Recovery would start from the bottom up though and it may have been too late. Could also have been baked by the sun while it was underwatered…
Gingerly remove the dead foliage and lets see what we find? @RedIAm
Please tag when responding like I did with your username @bob31 so I get an alert.
I took off the really bad, brittle leaves. There are still a number of leaves that seem fine in the middle but brown on the edges. The brown is also around other parts of the plant but underneath it seams fine.
My experience with other plants leads me to believe that this is a disease, not heat stress or underwatering. Diseases can be localized in portions of plants. Heat stress or underwatering affect the entire plant. I am not expert by any means.
I haven’t figured out when to harvest yet, I am still researching that, but I think I am close. Should I just harvest and hope for the best? Or do you suggest something else.
Thanks again for all your help. This has been a fun journey and I look forward to getting better over time.
