Mold???

It looks like gray or brown wet mud

Comme tous le monde le dit aucunes moisissures 😊 Cela dit belle plante pour une première 💪

If you can get a magnified view of those areas, mold will look like webbing between the trichomes. Can be hard to tell with naked eye!

I don't see any mold on the pictures, but a lot of trichome on sugar leaves, but if your worries then keep an eye on the plant and if you start to see a lot of white coverage it could be some kind of powdery mildew fungus.

If your humidity is really 35 then no. Unless you are spraying the plant for a reason. The issue is 1 of two things. 1 your substrate ph is not right. The other being not enough of correct nutrition. Flowering NPK ratio is 1-2-3. I see brown straight tips in pictures which is a potassium deficiency as long as they are straight. It then begins to spot leaves. So that would be the things I would look into. If your humidity was a lot higher then it would be possible. Good air circulation helps as well.

Not seeing any mold at, just trichomes and resin, looks like it's going to be pretty dank. Again you don't have mold growmie, your good.
