Need help - Yellowing leaves with brown spotting - Coco grow

I prefer to spray nothing when flowers are present. If I have to, I would mix isopropyl alcohol and h2o 50/50, and avoid flowers. I'm sure this would sacrifice some trichomes, but evaporate rather quickly with fans. Keep in mind that this is only a contact killer, so it would have to be a serious pest problem. All your best preventative measures should be taken while still in veg.

....and never spray with lights on.

Mr.furley I managed to get some more natural light on these trichomes. I only see a couple Amber, the rest about halfway milky?

The colored light can trick you with shadows.

Still a lot of clear, at least two weeks. If your going to feed only give 1/2 dose and id skip nitrogen completely.

Noted thanks 🤙. Was planning on riding it out with plain water and patience.
