The copper fungicide will kill most fungus,that still isn't septoria!

I wish we could get a science guy in here, to tell is what it is... A lot of folks planing shit on septoria, and while it might be a type of fungus that does this, there's no way to prove it's septoria...

There is a way, but it requires samples being tested in a laboratory set up for it. SO, in the meantime, instead of arguing about the exact name of this blight, let's just agree that since other methods (flushing, Cal/Mag supplementation, hydrogen peroxide wash, and epsom salt flush had no effect. And no bugs were present, can we not agree that it was a fungus and therefore the copper wash was the best solution (I found) to cure this blight. Along with the trail of symptoms, (see pics in previous post) yellowing between veins with brown spots on the veins that then spread up the leaves (starting with the lower fan leaves) which then wilt and die and spreads upwards as it progresses taking more fan leaves then sugar leaves until the plant looks sparse. With no sign of bugs.... you can bet I'll be going for the copper oil wash (Bonide) as the now proven solution. I'll just call it SOMETORIA! (Oh, and how DO you know it's NOT Septoria nmibud?)

I've had it outside,that's how I know what it's not septoria!

I see, so you had a laboratory diagnose your problem? Which lab did you use? How much did it cost, and how long did it take? What did you do to cure it? Or are you a botanist? I'm curious about your certainty. Please let us know so we can give your advice the attention it's veracity deserves.

Ahhh....so you really don't know....well, I guess we will all be taking your pedantia with a measure of compost in the future.
For those of you who wish to further your knowledge about plant fungi, the following papers from respected universities are one source of my "ignorance". I have found the following most helpful and I highly recommend reading these...http://ipm.illinois.edu/diseases/series900/rpd908/
ag.umass.edu/vegetable/fact-sheets/cucurbits-leaf-spots
http://msue.anr.msu.edu/news/tomato_diseases_are_on_the_rise
njaes.rutgers.edu/fs547/
and especially; http://www.missouribotanicalgarden.org/gardens-gardening/your-garden/help-for-the-home-gardener/advice-tips-resources/pests-and-problems/diseases/fungal-spots.aspx
I found these articles from university botany departments the most helpful in my research into plant fungi. NO ONE mentions cannabis, yet we all know few do. We have come to follow directions for Tomatoes as the closest available. Check these out, make your own decisions. But , do yourself a favor. If you see symptoms like these START with a copper oil wash. It takes care of most of the related fungi in these articles without harm to your plants. Good Luck!

I like to water with compost tea when plants are gimpy

Now you're just confusing people...and pedantia isn't even a real word.

Experience and 4 years of ag in school tell me you should look at potassium def as a problem.Your poor growing skills do not septoria make!

If you followed along, I already tried that.... the copper oil wash has done the trick. Grow now better than ever. Thank you to those who helped.

I stated early on to try copper,also prevention is better.Sesame oil and soap will kill bugs and ward off fungal infections.
