2–4 weeks into flower I’ve been seeing this brown hairs on some of branches. Thought it was gnats and took steps too eradicate and have only seen two on sticky tape in past week, but just was wondering what anyone else thinks? Please not broad mites or russett!! Is it heat? Nutes? Only on like one branch of plant. Has been about 90degress F past few days but I see it without heat on other strains. Not enough water? Idk. Been humid and hot and tough to keep below 80 past few days. Maybe I’m just freaking out. First two pics are the browning on a seemango and diesal. Third is healthy looking branch on seemango. I’ve grown both these strains without happening. Hopefully just heat stress. Thanks for your replies/information.
