Calmag will help that burn out. I noticed growing over the years cal mag is most important here for me. I don't spray or anything. . But when they look like that what I give them. Cause plant burningCheck out these new pics man they look really shitty I think they're shrvling up and dying. Think I need to take them out cuz I don't know what the fuck is going on with them. Fungus who knows. If I take them out I need to clean that tent with bleach and hydrogen peroxide. I bought it used for Amazon I didn't even clean it out before I put it up my stupid ass.
