Boa tarde, a meu ver se for só nas folhas de baixo pode nao ser um problema grave.
Mas sim falta de luz, podes fazer uma desfolharem e retirar essas folhas que não apaham luz.
Caso persista e se espalhe nas folhas novas ai sim podes ter um problema.

I couldn’t tell you if it is or isn’t septoria.
However if you’re struggling to keep RH up, I suggest going to a pharmacy and get yourself a humidifier. A cold mist humidifier would be ideal.
And as for the plant, get some Safers 3 in 1 spray and give your plants a little shot of that just after lights out so the plants can dry overnight.
I saw this post last night and I think maybe I might have the same issues with a few of my clones so I sent ahead and shot them with some 3-1. Even if it didn’t need it, I kinda did it as a preventative measure.

What to do with crispy curly fan leaves that do have some resin on them?, I'm already on flushing.Some fan leaves are starting to look a bit too crispy and curly, they do have some trichomes, I'm 3-4 days into flushing.
I'm not sure if the dry matter can "contaminate" the buds somehow, and don't know if I should do something about it, I'm planning to get some "bubble hash"
