I have ( over the years ) just accepted about a %5 loss of buds per crop . I did however start spacing my plants further apart and that helps . Also tried a fan outdoors and that helped a little . I finally just gave up the%5 and moved on , too much trouble . Texas has some brutal humidity , especially at harvest , sucks but those giant grasshoppers are worse . Sacrifice some weed to avoid chemicals that ruin your reason for growing your own .

Peace !!!
