Septoria!!!!!

I will not use copper because it will accumulate in the cannabis and I do not wish to consume copper in any form. Sulfur has worked in the past if I get ahead of the problem. I have noticed that certain strains are much more resistant to septoria than others, so those are the ones I will concentrate on breeding with for outdoor growing. Some summers here are very dry, and there are few fungal issues. This one went from drought to wet very quickly and caught me off guard. I have also noticed that almost all the new growth is spot free, since I began spraying, so we will see. It is always a race against something in late flower when you grow outdoors!

You may have posted before but it would be interesting to know resistant varieties you've grown. My ideal strain is a resistant early finisher. Funny how some growers don't give those two issues much consideration.

I have done a bit of reading on copper its very safe to use in veg state it is not systemic just like sulfur, It can build up in soil just like sulfur if not used correctly I thought you might have some insight on something i didnt know, both are considered very safe if used with half a brain. By the way Iam 64 in 8 days no youngster.

I have had Royal Kush do pretty well in those departments. My current most resistant plant contains Royal Kush, but it is a pollen chuck I made. But I have other phenos of this cross having more issues. Going to hit this plant with the 2 kinds of pollen I have and try to look at some of the offspring next summer. Plant limits keep me from doing any real pheno hunting , just doing the best I can. And I will be looking at some shorter flowering genetics from Oregon Green Seeds next summer, as well.

I'm also attracted to OGS. This year I was slack in prevention. Thanks for sharing.

Have you tried copper? I have never used sulfur because i found copper to work before I ever heard of sulfur. Copper has been a game changer for me as far as PM, MOLD, an black spot. But as the story goes once one can see black spot its all down hill from there gota get it early.

I can't bring myself to do it. Lol

If it wasn't so widespread at my spot I'd consider that
