Identifying rust mold

Or maybe I need to up the dosage on my Advanced Nutrient Cal-mag?
I'd just add epsom salt, it's dirt cheap and you can get it at the store. This is where opinions take over. Everyone does things differently, that's part of the fun of growing. I'll link a few charts for you to save.marijuana_deficiency_chart_jorge_cervantes-big.jpg leavedeficiencies.jpg cannabis-plant-problem-flowchart.jpg
 
Can be used right up to harvest, (directions say that for tobacco as well) works way better than baking soda from my experience, and I Bud wash too..

If you're reluctant to post pictures Google septoria & brown leaf spot and see if it looks like what you're dealing with before you start treating, be aware it looks a lot like a Calcium deficiency, look for the black ring around the brown circle, good luck

What does the black ring indicate?
 
PT, sorry that your plants are suffering. Did the spots start on the lower leaves first or where they clustered around new growth? Although it looks like you foliar spray caused some of this damage, it does look like a standard Ca-Mg def. Coco is notorious for this problem so adding a supplement is SOP. Growing for me has been an odyssey of f-ing up my plants and learning from my errors-it's part of the process. The hardest lesson was to not freak out and start throwing the kitchen sink at a problem. It takes time for a plant to react, so easy does it.
 
Thanks I watched Jorge's video. Didn't he used to teach Beavis and Butthead?View attachment 4236928
Yes he was their teacher..

And if I was you I'd wash those buds really well because moldy lung should be avoided if possible


Before you start adding things and spraying anymore stuff make sure that you're not locking out calcium, make sure your pH is correct in and out. Agree with Gabuto above, I see this type issue continually with Coco (it's very common) can't help you with coco, just septoria, and to me it doesn't look like leafspot, also by what you've said regarding humidity, so good luck!

Thanks! It didn't seem to start at the bottom, more at the top. I've usually added A.N. Cal-mag but have gone easy at times because I thought I was overdoing it. I wonder if i should try something more chemical/conventional. I also think I need to make a point of buffering my coco from the beginning. I think I might mix in some fort vee next time. So yeah it's a relief I don't have a nasty mold or fungus infection but Im sad I burnt up my leaves and threw off my ph and havent fixed my mag deficiency. Also a mold scare was enoguh to light a fire under my ass about ventilation so that's good too.

Thanks, good to know. From what i can see under 120x i cant find signs of spores or anything all that scary looking, especially inside the buds. I actually tried a little sample of a piece I trimmed 3 days ago and it was delicious and pineappley! Hopefully didn't colonize my respiratories with a Tree-jan horse. Grow-gan horse? There's a joke there somewhere. Thanks again. At least one plant is happy! I think I'll start flushing her just in case, although I think she'd benefit from a little more time (and a lot less baking soda, retroactively if possible) a lot of my buds still had those big white hairs and they turned Brown, giving the illusion of ripeness (does get you baked though). Sorry, inane rambling, nice to vent to people about my secret hobby.

Did you say before it's only rust if it has a black ring around the brown?
 
And a more soily medium.
When I run soil my preference is the Fox Farm's line. Ocean Forest soil and the bush doctor line. I run it at half strength because that soil starts warm. I'm not saying it's superior to anything else, I started on it and used it for years, but I keep it to soil. I run hydro currently.

Awesome thanks for the rec. Definitely planning to do side by side expirements in the coming months maybe years. Thinking coco by soil next time
 
Late to the party but from my reading an easy way to tell if it's rust mold is that it will come off on your fingers like pwm?
 
Is this thread for real, or is Paler just playing with everyone? Why was baking soda used on the plants? Trying to kill something? It's obvious that Paler has no clue what they're doing, no offense, but I'd toss all of the grow and learn more before continuing, like don't over do it with ferts for example.
 
How will he ever learn without failure? Sure he could paint by number and get a great harvest or fail even with a predetermined plan.

Only throw them out when you realize the money wasted on crops isn't worth the effort!

Hey there Mr. Pollack,
Unfortunately, this thread is for real. The editors of 420magazine recommended a baking soda solution for rust, which I may've mis-diagnosed. Its true, Im far from an expert, thus my seeking advice from experts. Hopefully I'll find advice wiser than yours. Seeing as how one of my plants produces delicious bud that gets me high, it would be a shame to toss it. I would thank you for your help but it didnt seem as though you really intended any. Enjoy your superiority, Happy Thanksgiving!

Thanks Shawnery I've been enjoying the whole process, even my recent mistakes. Believe it or not before a few days ago my plants were a gorgeous display even by non-beginner's standards, and I've begun flushing my first baby today!

Actually the overfertilizing bit is good advice. Thanks.
 
Not in this case when it is ignoring all my specific questions in favor of criticizing my clearly humble level of botanical knowledge. You have offered no methods in diagnosis, no knowledge on the smokability of rust plants, or any treatments for any of the ailments my lack of expertise has caused. I almost tossed all my plants a few days ago and Im extremely glad I didn't. Either help or don't but don't delude yourself like you're being condescending out of altruism.
