Fungus gnats or nitrogen toxicity?
Ezzjaybruhanswered grow question 2 years ago
You may be pushing N toxicity.. BUT that’s not what’s going on here.
It’s a genetic anomaly causing the weird twisting and whatnot.
Your 4th pic in the newest week 5 update shows unusual vein development on that fan leaf.
I’ve run a few CBD autos personally and they often have some weird genetic stuff going on.

That's definitely from nitrogen overdose. Ease off on the feed but also just plain water to flush out any excess nute

Definitely nitrogen toxicity. Dark green, Shiney, leather like, tips clawing down is all nitrogen toxicity. The brown tips curling up and in is nute burn. So your substrate ph is likely really low as well. It needs a lot of run off to correct itself. Plus about a third strength feed for some time.

You've got some nitrogen toxicity for sure, the dark green shiny leaves in one of the photos are a dead giveaway. Now as far as the twisted leaves this is going to be a genetics issue.

Autos reacting to All-Mix: Slight nitrogen overload?Pheno one showed very "leathery", weak, hanging leaves of dark green. Same time the fungus gnats had a run and the population doubled. After second LST also the stronger plant showed those signs on the younger upper leaves. Also curled down a little. Slight nitrogen toxicity?

Leaves have developed "claws" at the tips that bend downwardsMy leaves have developed "claws" at the tips that bend downwards.
I suspect there is too much nitrogen because I probably used too much root juice. (Approx 8ml, scale was inaccurate)
Now my question to the professionals: what can I do to fix the problem?

Am I overthinking things?Any idea what’s going on with these ladies? Or am I just over thinking. They just seem a little unhappy. Watered 750mil yesterday morning the last time before that was 500mil Saturday night. Could they be a little overwatered?
