Hi there I’m new to hydro growing & have encountered 2 issues firstly spider mites & now a leaf issue which I think is septoria lycopersici but need assistance as I’ve never had these & not sure what to do. Please help so I can learn what to do

what kind of light..
if anything that’s the cause of the leaf damage is the light being too close
