Controlling mold on Marijuana plants

A question from a fellow grower:

I’m a new grower and currently have 4 OG Kush in the flowering stage indoors.
I noticed powdery mold. I tested my PH and it’s good 6.5-7.0. I also tested Nitrogen and it was low (pink) I added just a touch, very little nitro to all 4 plants. The humidity is at 35-40% and the temp ranges from 80-75 during the day and around 68-70 at night.

The mold was worse on the bottom leaves, which I clipped. I purchased Neem Oil liquid extract, but haven’t picked it up from the store yet and plan to use it. Is there anything else I’m missing? I think my plants also may be over crowded. Should I trim more leaves to allow better air circulation?

I have a basement size dehumidifier in the room, works like a champ.

You may have answered your own question; I blame poor air circualtion. Inspect all planys and remove moldy leaves. Wash walls. Re-arrange in a more open formation, and, or, add more fans. :slight_smile:

Thanks. I did all that! Seems to be improving,

Keep us advised as to your progress; If you don’t mind. :slight_smile:
