Doctor, Doctor give me the news I've got a....

I ran this by another professional grower here in Denver, we've concluded there are NO insects. However there is obviously a problem.

Back ground. Super soil, week 6 flower problem started to surface last week , week 5.

We all no that in soil problem will show up often after something has transpired weeks before, The only thing that changed was a top dress of Fox farm dry nutrients bloom. It was out dated... by 2 years. (why I did this.....who knows ) every thing was fine some of the most beautiful plants I've ever grown. But anyway here we are. The plant started to show overnight Nitrogen Toxicity very dark green leaves and clawing on a scale of 1-10 a 7 in my opinion. so now the green is less dark, but this is been going on for a few days. Any thoughts?

I have been all over my plants with the 60x and I see nothing, I brought in another.. just to make sure.

I'm wondering if it didn't throw the mediums pH off. At first I thought maybe copper or boron, but i grow without either and never experienced any problems.
I'd look a the pH first, you have any way to test it?

you shouldn't need to add anything to a supersoil if it's really super. people will say add calmag and there's no way to know if this will help. it might and you could try a dose and see what happens. I'd tell you to use a well-rounded fert like dynagrow but there are other ferts in it and you have so much in that soil now that doing so could be dangerous. I say dynagrow because it has a bunch of nutrients in it like boron that might help you out.

Yea, I knew better. Every thing was running fine, I screwed up with the top dress, she's had nothing but straight water until today, And I gave her a compost tea, for the last few weeks.hoping that will correct any dysfunction in the soil

Ph imbalance is my bet, Its odd how I can grow such beautiful medicine and BAM things can change fast. Thanks for the reply

pH changes will the be the result of anything you put in the soil or was put there by the manufacturer. over the years, people have chased the pH issue but it's all for naught. You have to focus on the fert content in soil first and pH will probably take care of itself.

I did scrap the top soil off where I have amended the fox farm bloom dry nutrients,

Soil EC will affect you faster and harder than ph will.
Looks like the calcium may be locked out to me, probably by too much of something else not ph. Do you have an ec meter? If so please mix 30 ml soil to 60 ml water, mix vigorously and stick your ec meter in there and report results.
I'd bet a good flush is in order. If you saw overnight changes I'd be willing to bet its a salt stress issue.

Doesn't matter salts leach down into the soil. Do that slurry test I mentioned. If you dont have an EC meter flush those plants good till you get 20% runoff at least of how much fresh water you put in to flush.

With not using any nutrients for the entire 14 weeks, Then getting salt build up for one top dress? I did give it a heavy watering twice on its normal days, this last wateering I use a compost tea for the last few weeks of flower I will use water from here on out.

Entirely possible dude. If the shit you put on was too hot or threw the EC too high.
