Unfortunately I've got to talk about septoria in the beach house this weekend :/
I've got a post up with a poll because I'm not 100% sure..
Can anyone second that this is septoria? Had it years ago but didn't look like this, was always a brown spot with a black ring around it, but I know that septoria can also appear as yellow spots, thanks in advance for any help

but I'm 99% sure and I'll post what I do here for posterity, stay tuned & see how septoria is quickly eradicated!
Septoria is why I came on the cannabis internet initially about 4 years ago, I had septoria but didn't know what it was, kept thinking it was a calcium deficiency
Unfortunately I didn't notice it until lights off check so didn't have time but in 12 and a half hours at lights on I'll be waiting with a
copper fungicide spray prepared according to directions for all plants in bloom
I've already trimmed the most obviously affected leaves, I'll trim more before spray tonight
all affected leaves must be trimmed, cutting leaves in half is okay
already have done a cursory inspection of veg tent & don't see any evidence;
when I water this afternoon I'll do a closer look, if I do spray veg it will likely be with a
baking soda mix not copper fungicide
I don't use copper fungicide as a preventative, baking soda is adequate imo, I use copper fungicide only as a treatment
