40 parts homoginized milk to 60 parts water spray affected area and repeat as necessary at lights out or near sundown. If your growing inside then lower your humidity. Cheers

Mildew?
Hello! I've been noticing small white spots on some leaves. Can it be mildew? Or something else? I was getting this picture of a ladybug when I noticed them against the light. I don't know how, she's getting sun every day from 7 am to 6 pm, RH 40% in sun and 60% at night, 36 C.

PM or Nah?
Noticed some white spots on the tops of a few leaves. I’m days away from chopping and I’m wondering if it’s PM. If it is, what’s the best action to take at this point?

White misty layer on my leaves
Noticed the last days some light white covering on my leaves, if I go over it with my finger it disappears. Branches look good and green, no brown places on the branches, nothing wrong with the buds, they développe great. They are now in their last week. It's only on the leaves.
