Hey everyone, I'm noticing some small dots on the leaves of my outdoor that are eventually turning the leaves yellow. Had this problem last year and thought it might be fungus as we have some high humidity and lots of rain every August, but I was never able to really identify or treat the problem and am wondering if it's leaf septoria or maybe a bug or nutrient defiency problem. Anyone know what might be causing this or how to remedy? Thanks for your help!IMG_3980.jpgIMG_3982.jpgIMG_3983.jpg

This looks like to be the same fungal infection I'm fighting right now and its a bad one. Its called septoria leaf spot. Pull and burn or trash bags all spotted leaves and spray with a fungicide. I'm still trying to look into what the best one to buy is but I only have bee safe 3 in 1 organocide idk if thats enough on its own. Let me know with your research if you find a marijuana safe fungicide thats know to be good for septoria leaf spot thats cheap. I found some online but I am hurting for money right and have already dropped so much into this grow its sad to see this happen. First year I ever had anything like this. Its from mold spore that can survive thru the winter on dead foliage and spreads thru wind and rain. Its guna be a battle good luck my friend. Keep me updated on how they go wishing eachother luck

Had it 2 years in a row! My friend made a concoction out of sulphur, (no copper), which I sprayed in July and August, and it might have saved my grow this year. Now it is dry and sunny, just need to hang on for another 2 to 4 weeks. Lost 6 10 foot plants to it last year.

So if I do buy a cheaper one go for a sulfur based one. I'm guna make the order tonight. The bee safe 3 in 1 seemed to hold it at bay but I think I need something stronger
