Hello, Brazilian greetings to you.
Congratulations your plants are beautiful.
you commented before that your plants are getting rain, I have several in the same situation (Agroecological guerrilla, in search of the True Brazilian Sativa)
as I never planted in a greenhouse, I have some doubts:
does the chuca disturb? decreases the power? or are they just problems with fungi in more susceptible varieties?
