What is this? :(

Hi!
My plants are outdoors. Almost starting flowering.
What are those yellowish spots?

(white stuff is just an anti fungus i sprayed yesterday, in case those spots are some kind of fungus)

It may be septoria - hope not! It starts at the bottom and works it's way up - eventually taking over every leaf. It's in my soil and I have used landscape fabric to keep rain from splashing the leaves. Also considering container plants. It's happening all over and has people looking for septoria resistant strains.

Well, this are top of the plant leaves... lower leaves dont have spots.
It looks like septoria
Good news is that only a few leaves got spots. What can i do?

Insects may have brought it to your plants. You could remove the infected leaves if there aren't too many. Practice good hygiene before touching another plant. Allow lots of air flow around each plant. You've already been using a fungicide as a preventative, so perhaps keep doing that - if possible use more than one type of fungicide.

Different strains will react differently to septoria. Some may be devastated and others will get a few spots but you will be able to finish the plants. No way to know until you complete the grow. I've dealt with septoria for 6 years, no know cure once you have it, but I have still managed to harvest plenty of quality outdoor despite that. That said, I can't definitively say that is septoria from just those pics.

Perhaps one of the residual detriments of legalization is that many growers are pollen chucking to make different strains and save money. If either plant (donor/receiver) has septoria, then those seeds too will produce plants with septoria - further perpetuating the problem.

I didn't know that septoria can be passed on to seeds. Lucky for me, I haven't encountered septoria.
