white filmy residue on leaves

hey guys. i just noticed that on some of my plants, there is a white, filimy like substance interwieving in between the top few buds and the leaves attached to them. it looks almost like deoderant when it sticks to a guys (or girls lol) underarm hair..u know what i mean? can any1 diagnose this without a pic, i can prolly get 1 , but i'd rather not go thru the hassle if u can determine what it is off the bat. the plants have been flowering for a good week now, and its not cold enough to be mold i dont think (hope not). maybe its just the after-dew of the SPRAY and GROW i sprayed on them or maybe the pesticide, but i duhno. i just gave them a dose of nutes, but i watered with them so thats not it. any ideas? thanks alot

 

I'm not sure without a photo.

 

This could be powderey mildue. It is a problem due to spores entering the grow area and humidity being too high. More ventilation or dehumidification will help as will a filtered air intake. To treat this problem you need a sulphur burner. Follow direction for usage for 3 days in the early lights off period. This treatment is the best and a burner and sulphur is inexpensive. What is your relative humidity and do you grow indoors? BOG

 

no i grow outdoors

 

It could be left over residue from your spray as you say. A poet and I didn't know it. Is it a slug trail?
