Could use another opinion

I've got a potential issue, but maybe I'm paranoid. I'm seeing clawing on all 5 plants plus a little wrinkling on just 1.
I've got 5 various strains all in the 4th week. Just started feeding 3 days ago with 1/4 strength age old grow 12-6-6 for all but my two auto-flowers (fed autos just H20)
Medium FFOF/perlite 3:1.
Temps/humid for the last 2 weeks--
Temp:76-86
Humid:30-50
I realize that my temps aren't consistent and am considering that could be the problem.
I typically wait until soil is dry, or the weight of the pot has lessened--so overwatering I would think would be out of the question. And leaves look pretty healthy so N tox doesn't seem to be the culprit.

Always helps to have another opinion though! Thanks

Definitely looks like N tox to me. Even your new growth has some burn. They don't always go super green with an N tox. They also look a little dehydrated which will make that N tox more noticeable. Heat stress could also be a factor.

I would say it's more than likely a combination as I see signs of N tox and under watering. Humidity is a little lower than I prefer, so I'd say it's a safe bet.

Thanks for the response.

I began noticing these symptoms yesterday (2 days after the last watering and 1st ever feed). I'm wondering if it's the age old with the FFOF...and shit 1/4 strength in the 4th week feels pretty standard no?

And yeah 86is a bit high, but I've been able to make adjustments

I don't use FF so I can't compare accurately. I run a composting soil so it usually lasts beyond the grow with a transplant between veg and flower.

In any event, I would say that it's absolutely possible. I'm 98% sure you have N tox but only 50% about the watering. They are drooping a bit but that could be the combination bringing out the tox even more.

I dont see any tox here... this is N tox

FF feeds your plants for at least 3 wks...I wouldnt give anything to them till you see signs the plant has used up all the nutes in the soil..mildly overfed per your pics...water lightly till the plants start looking perky again. DO NOT FLUSH...it will release more nutes in the soil...thats why i recommend watering lightly for awhile

You have temps near the upper end and humidities down near the lower end,this will cause the plants to transpire more and nutrient levels in the plant will rise.It does look like the start of an n tox,id back off a bit on the feeds and monitor new growth for a week or so.
