ANY IDEAS DARK GREEN AND CURLING

all my plants are doing amazing all getting same light and feed and all in tent with temp at 25 and humidy at 90 i have just one plant thats growing fine just dark green and curling leaves any advise is appreciated thanks in advance...

In imo from my own personal experience the twist in the leaves plus a slight claw are telling me it's a problem with the roots or nutrient ph in my very humble opinion as I am by no way am I a expert just my experience

Thanks for your input m8.... just weird as its the only one and had no different treatment ill give her a flush and give her a strong root stim see if she improves. Thankss again buddy

They don't look in danger. Well fed, just watch to make sure nothing goes downhill or changes too quickly.

Fed nothing but the best lol but yeh will defo keep an eye out for her the more I look and think about this im thinking there may be a problem with the roots slightly gonna give her a flush and some stress relief. And feed her some music lol

If I have nitrogen toxicity then whats the best way to go about this??? Would it be best to flush till a good amount of runoff then maybe flush again till I see lighter leaves at the top??

No flush ....... flush a toilet . Plants look healthy and will exhaust excess over time .

So just use plain ph'ed water till it gets right then?

Pictures without the lights on and just a camera flash is best for diagnosing true plant color.

What are you using for lights and how close are they? Tacoing leaves where they curl up on the edges is usually the result of excessive heat or light. Your temperatures at 25 are good but the humidity is way too high.

I'm using a 2000w led samsung chips above them plants at 18 inches above the canopy yeh my temp is correct humidity is a little hight but wa stold anything from 50 to 90 in veg is perfect its not light burn as they wouldn't be dark green its defo alot darker green from the rest... from what I have read and been told so far it all seems to indicate its N toxicity as its got all the symptoms just need to no how to get it back to a nice light green.

The others plants are the same strain? Is that plant the only one of that strain? Different plants will react different to the same amounts of light. It looks like your lights are a little too close some of the other plants are tacoing too.

As far as nitrogen toxicity you're probably right. It's hard to tell from those top down photos but it looks like some of the really green leafs have the tips curled down which in conjunction with your super green leaves would indicate that N tox. Simply reduce the amount of grow nutrients you are feed it and it'll be fine.

Yeh they all the same strain gorilla zkittles these lights give off next to no heat i really can't see it being the lights to close but I'll raise them slightly see if it helps they maybe to close tbh as they dont seem to be growing..... well they ate but just pure inner noads all growing through im trimming all the inside fan leaves to open up the canopy to allow the middle of the plant to grow they just staying really small and busshy the nodes are so tight together its untrue I no this is a good thing but dam I wanna get them taller now they to bushy..... ill raise the lights or I could just turn them down as they are run off mean well drivers so they dimmable. I'll start feeding them quater strenghth for a few feeds see if they respond hope it pulls back will it just all change color or will the dark green leaves just stay green and the the new growth be a lighter green?? Just so I can see the change?

Tightly grown nodes is an indication that the light are close enough not to need to stretch.Raising the lights forces them stretch out. Your new growth should be a lighter green when the nutrients strenght is reduced and the darker leaves will lighten up as well. Dark green is an indication of to much feed in my humble non expert opinion. Also research the strain maybe just grown small

Just keep checking the runoff ph
