i have an aeroponic sytem with a 5 gal res that i use technoflora BC nutes in. i have 12 plants now, but two days ago i had only 6, they were doing great, little youngsters but growing and rooting great. then i brought over some of my plants that a friend was growing and i noticed that the roots were brown/golden, i took them out of their pots and rinsed them all off with water and put them in my system with my other plants,,,, i woke up this morning and checked my girls like i always do and low and behold the roots on my youngins were brown as well. is it possible for it to spread that fast and how the heck can i get rid of it.... should i just pull the ones i just got and try to save my little ones or just trash them all... OR is there a way i can save them all.... note : my big ones that i just got are 4 weeks into flowering but they are droppy and root rot looking... PLEASE HELP
