Could cause a tiny it of stress to the plant but if the leat if 70%+ dead its just worth it to take it off. Mold puts its target right on more vulnerable plants, and then speads quick if you aren't on it - just not worth it to me. But has anyone else used MOAB? Do I really need to decrease my PPM of my blooming nutes by as much as 50% like the MOAB says?
