Hello again, in my previous question they told me ...

anyone who had wpm will tell you, that leaf didnt came from this plant ( maybe flash and some crazy milk spray can trick us to "seeing" things ), but if i would have such infected leaf, most of plant would look same . something not adding up here ...

"spray mushroom insecticide" = no Nothing in flower. wash your buds after if it come into contact with it. I can't say for sure whats wrong with this plant. If its WPM or if its something else, If the leaves are isolated and removed and its not progressing anymore maybe its ok? could have been a one off thing but that's rare. Normally spotting like that on the leave could mean a few other things but when its brown/gray/black it scream fungas/infection to me. Or something might have been dropped on the leaves and it burned em?? Monitor them, proceed with caution, be ready to take action if needed and relize that action might be to cull the plant.

nothing you can buy over the counter will be effective against fungus. Even stuff that is available to large commercial farms is not effective. Also, you absolutely don't want to spray that shit on anything with flower growing. None of the anecdotal remedies work... just a bunch of people lying to themselves and spreading it all around the plant wherever it drips, lol. Just a bunch of smeared fungus all over stems, leaves, buds etc... plus, cleaning the surface does not rid the plant of fungus. it grows beneath the surface, too. any antifungal that is "systemic" is also dangerous to use in vegetative phase because it stays in the plant and can still poison your flowers later (see "eagle20" as an example of that context) when you see fungus, you can try to amputate it and remove infection from area ASAP... might get lucky. If it's as developed as that leaf, it's most likely all over the place as that is several weeks of fungual growth, minimum. It's spreading spores after 3-5 days of getting a foothold -- when you can barely see a spot of it. if it is miraculously isolated to that one or 2 leaves, you can try removing it and pray. if other plants are clean, you may just want to remove the entire plant that is infected. Up to you. The leaf shown doesn't match the plants shown... it should be all over if it has had time to grow that much on that pictured leaf. either something is fishy with this grow question or ....???
