If it were me I would go ahead and use it.I've heard good things about Safer....if you are in week 6 right? Turn your lights down and make sure you have a fan going until the stuff is dry and keep your lights VERY EASY on them for a day or two. Work to get your rh down as well.

Jerry, I'm pretty much telling you how I would treat these plants if they were mine.....mold and fungus scare me to death and I'm as careful as possible about it. When I found mold in my buds it was in the largest ones and you literally had to break the buds open to see the mold. I actually found it by accident while doing something else.....and I had pretty good conditions going on at the time too. Stress to your plants will allow these things to get a grip and hold on; just fyi.

Yes, I would spray, I woud get an oscillating fan on them and get your rh down to the thirties if possible. If you can improve conditions you can get a handle on the mold and limit the damage....assuming there IS mold.

One way to check imo is to VERY GENTLY pull on the bud and sugar leaves. Moldy ones will break right off and be mushy....that's actually how I discovered the problem with mine. I pulled on a sugar leaf to move the plant and it literally just broke off. When I looked very closely I could see the problem.

Good luck.
