I'll answer your question in two parts.

Yes, water curing would allow you to foliar feed, HOWEVER, during the flower stages, foliar feed PROMOTES mold as well as insects. So its not generally a great idea.

Yes, you can use pesticides and your mold preventatives, but.... Would you really want to smoke that? No matter the cure, you know whats gone into it, do you want to risk hurting yourself, or anyone else? Unless your using RO'd water and doing a 14 day water cure, you can't be sure you get it all out.

Good luck! (I water cure)
low_rdr Reviewed by low_rdr on . Questions on Water Cure I have read up on the water cure and realize all the pro's and con's of this cure process. I have read water cure will eliminate the need for a flush since the water will draw out the excess nutes. My question is based on this factor. Would water curing allow you to foliar feed? Could you use organic pesticides through the flower cycle as well as mold preventives? Rating: 5
