I will keep this post update regualy with pics as i know you all like your porn even if it is a bit leafy also any1 wanna ask me a question on the grow go ryt ahead. I am in need of help though . as you can see in the pics i am haveing problems with 1-leaf curl around the whole leaf both up and down, 2- leaves turning a full 180 around so there faceing upside down? , And what i think is most important is brown looking scortch marks that are usually in the middle of the leaf and some with small holes in . I am most worried about if these are pest problems. Any help is GREATLY welcomed........
