Using some Neem oil and hydrogen peroxide ONLY ON MEDIUM (since I'm in flower), to get rid of these dumb fungus gnats I think they are the reason for the brown spots forming on the leaves. Installed a trellis this week to help spread out the canopy and improve airflow, however when I did this my dumbass accidentally snapped one of the colas, luckily I think it'll be ok because it seems to have only snapped the outer skin layer on only one side of that stem (I wrapped a piece of duct tape around the little snap to help secure it). This week went well I think I've got the fungus gnats under control, the stem I partially snapped still looks to be completely healthy and growing well so no complaints here successful 2nd week of flower👍🏾
