  1. There was a Vine that snuck in in a couple spots of my garden and the low leaves we're affected as I could see it on the vine as well as the leaves it was connected to.

  2. Dear DeBacco University, greetings from Australia , firstly you have been such a great help to all us growers, we have tried your recommendations with Peroxide for seed germination and was blown away how much faster they germinated.
    We have a bad problem with what looks like in your video about “Septoria” that has wiped us out for the past 2 seasons, well at least with the thousands of hours of research our problems looks like the picture of Septoria, but need your clarification that it is definitely Septoria and not some other problems.
    I have a picture taken yesterday Tuesday January 31, how can I show you the picture of the leaves we have ?
    Do you have an email address so we can sent the pictures to you ?
    Please Please kindly reply, we need your help URGENTLY 🙏

  3. It’s almost like tomato plant blight. It’s impossible to control. It’s prevalent here in Southwest, Va. If it’s damp it will show up in late august/early September. It doesn’t matter what preventative measures you take. I’ve fought this stuff for 3 seasons.

  4. My plant was placed by a small black walnut tree(i think) which unknowingly had leaf spot. It wasn’t there last night and is this morning. Its been raining the last 2 days😢 so quick i didn’t see it coming.

  5. Tnx ….i think i have it on one plant …i thought it was some soil problem creating root problem ….causing deficiency ….can hydrogen peroxide spraying eliminate patogen?

  6. I know this is a little late, I have my cannabis plant but its not leaf septoria, its some weird spots that looks like rust at the base of some leaves while I can see regular healthy ones have no visible spot at the base. I don't know if this will affect it in anyway but it seems to not be spreading so? Should I be worried

  7. My heart is broken, had a beautiful Colombian haze plant, stupid ass septoria is destroying it very rapidly, i thought PM was bad, septoria is very aggressive if you spot it act immediately and cross your fingers, its a devastating disease , my poor haze plant had at least 8 weeks left no way in hell is it gonna make it, be careful out there esp with longer flowering varieties

  8. So far I really like your content. You give clear descriptions of the things you are talking about(/w pics), and you haven't tried to ramble off technical jargon, in a way to make yourself seem knowledgeable. I just started growing myself and of all the 100's of hours of youtube growing content i've watched, yours is my favorite so far. You actually describe everything properly without seeming biased toward certain methods while clearly stating the reasons why. What I like the most of all is all the trouble shooting you show for the different diseases/ deficiencies, etc.

  9. I loved how you covered prevention. I just wish you would have covered the control a lot more. Are there any sprays? Do you remove the affected leaves? These are pretty important things that people watching this video are trying to find out. Cheers. That being said you still taught me things, which I'm grateful for!
