Septoria / leaf spot diseases, mildews etc can affect seed stock afaik.https://www.nature-a...g/septoria.html
Usually just after flowering starts is when they become noticeable to the eye. These pathogens can be systemic within the plant/ seed, and lurk in the soil waiting for optimum conditions. Best way to avoid problems is to start with quality seed stock.
Most moulds are no good. Give your plants good growing conditions and treat when conditions are unfavourable.
Good luck with the grow.
