Is it Nitrogen toxicity or overwatering?

Looking for a little help on this issue. I'm having trouble making my mind up on it... Should I flush it or just let it mostly dry out? Leaves are dark and shiny. Some curl the whole leave, some just the tips. Soil is a lil funky. It's mostly coco but was running out and had to add some cheap potting soil with it to have enough. I did throw it right into flower without any buffer time to flush out extra N. So not sure what it is. Any help or suggestions would be great. Thanks.

Got pics?

I can try... Light is on.

Here are couple funky ass leaves. Nothing is yellow/brown. Soil is damp but not soaked. Bottom leaves are crispier but still green. It is a new strain to me. And not sure what it is.

I'd go N toxicity, because many are sharply curving down at the tip.
I think overwatering will be a more uniform, wiltier look.

Back off the N some. You're not blasting them with a fan are you?

I've stopped all N for the moment and yes a fan is pretty much blasting it off and on

Should I give it a day or so then flush before I give any more nutrients? Or should I just feed with like no N on normal schedule? Or should I just flush right now? Leave the fan off of it for a while?

Damn cheap ass soil... I knew it was gonna come back to get me... LoL

What's changed recently? You mentioned throwing it right into flower, does that mean you recently acquired the plant, or had it somewhere else in veg, then moved it to your flowering spot and now it's wilting?

Did you raise it yourself in coco?

I acquired it from a friend who didn't have room for it. I repoted it and used the coco mixed with cheap soil. Had it in veg room for maybe a week while it adjusted to new pot then right into flower room 1000w. Gave it a early bloom dose and now it's clawing pretty good it seems. In flower room for 12 days now. The other grower and I use different nutrition. I use GH and he uses Nectar I think. My ph maybe a lil high but not crazy. Mid-low 7s. What's the best course of action? Just sit tight and see what happens or should I be pro active and give it something? I'm torn. LoL

I'm kind of a noob, so I wouldn't listen to me too much, but plants respond quickly, so I'd look at everything that's changed and when she starting giving you negative feedback. Sounds like she was happy with your coco transplant and was happy in the veg room and didn't show these signs until you moved it into the flower room, which means the main changes are light and presumably heat and the water/feed schedule. To me, your plant looks like what I've seen when transitioning an indoor clone to full sun and not so much what I've seen from heavy nutes, but I don't see any bleaching and it looks like the inner leaves are suffering too, in which case I'd ask...I assume it was in coco before your transplant and you're used to working with coco and aware of how it dries much more quickly than soil and even moreso when combined with a hotter light and more fan? How frequently are you watering/feeding and with how much runoff?

Reading through the page on n toxicity on growweedeasy, it does seem like n toxicity. I imagine you'll know shortly if you start seeing some yellowing. Think I might go with a water flush at the next water/feed schedule and water only for a day or two and then ease back into the new flower schedule, 1/4 strength for a couple/few days, 1/2 for a couple/few days, 3/4...etc. Also agree with the guys that it should be more uniform if it were overwatering.

Too much wind will magnify the looks of N tox. I had it happen last winter. That's why I asked, I know what it looks like. Get the fan set up different to where it's blowing in an indirect way. Maybe just a straight water on the next scheduled feeding, then drop your N uptake a little after.

My thoughts also, I have 1 plant with same issue

Hey thanks everyone. I've since removed some new soil that was on top and probably rich in N and I flushed it earlier today and now just waiting to see what she looks like tomorrow. Hopefully she'll perk up. Thanks for all the input and helping me make up my mind on what to do. Lol. Sometimes just need to hear someone else say it. Gotta love this site!!

Update - gave a good flush yesterday and probably still to early to tell but she is definitely starting to bounce back. Growth has started to pick back up it seems. I haven't feed it anything since flush. But will probably go straight water on the next one when needed. She looks like a pretty sativa so hopefully she'll produce something unexpectedly nice! I named her "Phat Chick". LOL
