Solution for nitrogen toxicity in soil?

I'll kill these plants yet.

So far I have dried these plants out for 4 days. Then for three days. Had them up to 94% humidity where they would droop after down time for hours. Now they are showing signs of nitrogen toxicity.

Growing conditions uare.

Legal state patient grow.
Sour diesel auto fems. (Or so I was told. Only got two good plants and a mutant from five seeds)
25 days old. Only 12" tall :(
1000w MH
Can't tell sex yet.
Roots organic soil mixed with 25% growstones.
Seedling section Light Warrior.
pH adjusted from 7.5 to 6.5
Town water bubbled for 48 hrs+
5 gallon fabric pots
Lots of fans.
Temperatures now pretty steady at around 77 degrees
Humidity staying between 35 and 65. Most of the time at 45% now that I changed my ducting so that the fan is on all the time instead of a temperature sensor.
The soil feels moist one inch down and the pot feels heavy.
The only LST I do is leaf tucking.
4 days ago I gave them a light dose of photosynthesis Plus to about 20% runoff. Since it had been about 4 days and they were drooping. I gave them one quart at a time half an hour apart. Took 3 quarts. This is the only additive I've ever put in their water other than pH solution.

Yesterday they looked too dry and felt light so they got two quarts about 15 minutes apart and had minimal runoff. I gotta stop letting them dry out. Maybe I have too much perlite and growstones. Maybe I just have to stop worrying about over-watering them.

Now I have my first simple organic tea brewing for 12 hours so I will be able to give them water two days after previous watering with the Brew. That will be 36 hours brewing.

I think I now know what I did wrong . I want to know how to fix it.
Should I give them just water for the next watering and dump the tea?
Water to run off or not?
Should I give them the tea? I was going to add a little bit more photosynthesis Plus and 1/8 grow nutes but think I may want to wait.

Oh and do you guys prefer the image in thumbnail or in the post?

This only shows one of the leaves but there are about four or five of the biggest fan leaves that are dark and have the claw. New growth looks good to me.

Not nitrogen toxicity, let's see some of the other plants
 
dont panic..go slow.. its minor....the plants look good and will recover with no damage

you are having an issue with magnesium
and iron
and they might be "slightly" over fertilized

I don't think you need to flush
I would start by watering with only plain phd water and 1/4 to 1/2 tsp Epsom salt (magnesium sulfate) per gallon
only water when the pot is extra light

first instinct is to say you need some calmag and Epsom salt
calmag has calcium, magnesium, nitrogen and iron ...Epsom salt has magnesium and sulfur

but first lets make sure your def and not suffering from lock out from over fertilizing

with plants that size and pots that large im surprised you need any nutes
what are the NPK numbers on the bottle of nutes you have and how many mls per gallon are you adding

I did not added any nutes before those pictures . Only photosynthesis plus until tonight when I gave it some aerated compost tea. Just ewc compost and molasses. Still no nutes.

sorry I don't know what photosynthesis plus is

in that case
I would just add 1/4 tsp Epsom salt per gallon to every watering or 1/2 tsp every other

for a quick fix spray them 2x over 4 days with 1/4 tsp per gallon Epsom salt
 
they might also appreciate about 5mls per gallon of calmag along with the Epsom salt watered into the soil

thatll get the iron up and help with the yellow tops and itll help prevent the calcium def that shows up around week 4 or 5 in soil
