I have 2 Feminized and 3 Autoflower.
Feeding seeds from this site.
Using Fabric Pots with coco and perlite.
PH tested each watering. Range from 5.8-6.2
Jack’s nutrients
My plants are outdoors but in a greenhouse
The daytime temp ranges High 122 Low 84
The nighttime temp ranges High 78 Low 47
The daytime Humidity ranges High 94 Low 30
The nighttime Humidity range High 60 Low 16
I have 3 small fans running in the day.

They started getting brown spots and some curling a few days ago. Some white spots too. Any help would be appreciated. Thanks

Hello, your pics didn’t load. On the way bottom of the post wait till it says 100% before post, I think reposting the pics will help a lot of the grow pros.

Thanks I saw that and wasn’t sure what to do. I will repost.

I’ve tried putting pictures in and they won’t upload. I got one to upload in one of my replies. I will continue trying with the others.



Do you mean 122⁰? F. That is way too hot. can u get more fans or exhaust or run an ac out there. Maybe keep them out with a shade or lean to over them.

Check under leaves for bugs.

Yes 122 F😢. My plants are in a greenhouse and if it gets in the 90s which it was today it goes into the 120s. I just ordered two more fans and am hoping it helps. Otherwise I am thinking I need to get rid of the greenhouse.

I have been spraying for bugs every 3-4 days with dawn and water. I did use another spray once last week but diluted it because it was the first time spraying them with it. I plan on doing it again with the full amount it calls for. Thanks

Jack’s dead bug spray can be used right up to harvest.

Thanks I will give it a try.
