White dusting on fan leaves??? Please help.

Im on the last couple weeks of thos grow over the last couple days ive seen white dusting on the fan leaves mostly nothing is on the buds or sugar leaves but some smaller leaves have it. I just got a papper towel with warm water and seen if it would come off and it came right off like it was dew in the morning. It actually looks like dried up dew but can someone give me other opinions???

sounds like mold...are you growing in high humidity?

Did u spray anything on the leaves? Like fertilizer? If yes then it's dried salts. If no then it's powdery mildew. Since ur so late in ur grow I wouldn't spray anything. Just ride it out. U can bump up the temps since fungus don't like warm dry conditions they like cool and wet. Hope that helped.

use 2% milk bro! 1 part of 2% milk for every 10 parts of water. put it in a spray bottle. wash your leaves down. itll remove mildew or mold

Its powdery mildew by the sounds of it. Here is a good link with lots of help/tips

I havnt sprayed anything on the leaves.
Its a outdoor grow.
Night times been a little humid.
Can i chop early?? I still got 1/4 inch white pistols maybe smaller??

U can but I don't know if I would. U can still get mold out doors. I would try to fix the problem first before I chop. And get the best out of ur plant.

Oh...outdoors. U can't do much I'm afraid. U can spray all kinds of stuff but ur too close to harvest so I wouldn't. PM is best prevented by weekly sprays or dust applications beginning before u even see symptoms. Once the leaves show residue on them those leaves are toast. They won't turn around even if sprayed. Only thing u could have done is keep it from spreading.
If it were my crop I would remove the affected leaves so spores don't spread to the buds. What do u have left, a week? Maybe two? I would start removing the worst looking leaves and continue all the way up till harvest. Even if u have no fan leaves left by harvest. Don't want PM on your buds.

Horse tail grass tea. Good/safe to use right up to harvest !
Brew it as directed on the box and cool down. Put in spray bottle and use it....

Available on line and at some health food stores. This is an herbal tea. Plants LIKE it too.

I agree with dr.who, Ive tried milk honestly it starts to smell like milk lol...go natural, as of now you can not cure that mold its spores in the air in your grow area..all you can do is control it, ive lost plants due to powder mildew..it feeds of the nutrients that the plants need, and in flower its worse.. try neem oil...it helps restore the leaves as well as fight the mildew...only treat right when your lights come on though good luck
