Nutrient burn symptoms?

Google leaf septoria... It's very common in all plants. Autoflowers seem to be susceptible more.... I think alot of people overlook this as an issue. Honestly if you go outside you won't find a tree without it... Good thing is it's only an issue with the leaves.. it's spores and can spread to other leaves. They die and drain energy needed for the plant.. remove the leaves you see it on and you should be fine... Clean your tent with bleach if you can take your plants out for an hour or so
