I hope this goes well.
Choose Gelat. OG because of the reviews for the uplifting effects of this strain. 72h in the paper towel and the seed germinated well.
Only one plant to begin with.
Small setup because of lack of space.
Medium -> 60% coco / 40% worm castings.
In this first week, I'm going 24h of light.
Trying to keep RH in the 60~70% inside the tent.
Only on one leaf of one plant. Is this some fungus or virus?
It looks a bit like coffee rust, but I couldn't find anything else like it.
How should I proceed?
Thanks in advance!
Pretty certain this is Leaf Spot Fungus otherwise known as Rust Fungus... and you'll need to jump on this quickly as it spreads fast... it spreads by spores that you can't even see so don't think you've got any time to waste here... I won't go into all the details of what you need to do as this article is very thorough.. Do give it a read and get going so you don't lose your entire grow...
