Hmmm IDK about zone treatment. I use mesquito dunks and throw them in a sock with a weight leaving them in my mix tank. I am more concerned about the spidermites. You need to invest in some quick pest control. The cheap but not effective method is ladybugs. The more expensive but very effective method is using predator mites such as these:i just used some zone treatment on the girls. how often do i need to water with this stuff to rid myself of the larvae? and whats a good remedy for mites on wk 2 of flowering?
