Mycos causing N tox?

I doubt it. I know people that put Mycos directly on the root ball and in the soil before they transplant young plants into bigger pots. These young plants would get badly burned if rapid N toxicity was caused by mycos.

Good point. I am only wondering because I have a grow going (4th week or so flower, about 2 months veg) and I have only used high N ferts twice (both 1/4 strength doses of Grow Big, both while still in veg) and then last Saturday I sprinkle a small amount of Great White on the dirt and then water w pH'd tap, and the next morning all the sugar leaves on the top few nodes are looking N tox'd hard. The rest of the leaves look perfect, and this issue literally happened overnight. I will add pics here in a bit when the lights come on.

Because it takes a couple weeks to get established and is easiest to apply at transplant, it needs to be done early to really pay off during flower. But the fungus will very much be alive during flower if your grow is dialed in.

I know you are more knowledgable on organics than me. Running my first go of a version of super soil now. I can for sure say that that azos shows with in 6 hours of feeding on my plants. Just darkness
This is after 3 waterings with the azos.....which is when I stopped. Now once every ~2 weeks in veg.

Ok so am I way off on the N abundance here? I guess it kind of looks overwatered, except my soil was pretty dry when I watered it last. I also don't understand why only the sugar leaves appear affected, while the fan leaves all appear perfectly fine. According to runoff, my pH has been in the low 6s so I don't think it's pH related.

Every strain is so different but sugar leaves in my experience do not follow the normal "healthy leaf" judgment system. As long as the fan leaves are not neutered off use those to judge your plants happiness. Also, usually if you think you could be over watering you probably are. Hell even when I think they're a day or two behind on watering they look the best. I've only seen my plants under watered once. Over watered almost every grow.

I could just be over complicating things I suppose.the Friday night before the watering in question the plants themselves were feather light, and my fingers went all the way down and the soil was dry all the way through. I guess since the fan leaves look fine, the pH is always within normal ranges and my environment is dialed in then I shouldn't be too worried. I think the speed in which the issue occurred is what worries me the most, like seriously 8 hours maybe haha. That plus those leaves look so nasty I can't help but wonder if something is wrong.

I've never grown something as sativa as that. Leaves don't look too bad. Could always be happier as in praying some. Looks like some nute problems in the one close up. More pics is more information. If new growth looks fine and old is still ok the. I'd guess too much water

so I decided that since I hadn't yet flushed this grow that I would go ahead and do it...all 5 in 5 gallon pots got 5 gallons tap pH'd at 7.0 and the clones in 1 gallon pots all got 1 gallon tap pH'd at 7.0...this morning I checked on them before work, and they seem a little overwatered (obviously since I just flushed) but we shall see in a couple days if we're better, worse or the same.
