Nitrogen overload please help

Hi all, having abit of a nightmare with the critical cheese I am growing and need a bit of advice please.

Have 9 in an 8x4 - in coco.

I vegged them 5 and a half weeks final pot 11ltr and flipped to 12/12 last Wednesday.

i go to water them yesterday and they are all clawing downwards and look dark green - some have a slight yellowish tip but bare visible. Some newer branches look like they can't hold themselves up. This surely is nitrogen overdose as I've been reading
And it's pointing to this.

I have been feeding them 1.3 ec between 5.7 and 6.1 ph. Usually 5 litres a day making more than enough run off.

thing Is I only realised properly that there is a potential major issue until I had watered them another 1.3ec !

So I diluted the nutrients to 0.8ec and re watered (so about 9-10litres per pot went through them yesterday as opposed to 4-5litres)

I have a bio green matt on thermostat, as well as a 1000w oil rad in an mdf box on a root it thermostat and temperatures haven't gone below 21c but have gotten up to 30c for some periods but not showing heat stress canoeing so I don't think it's an environmental factor.

I am still feeding growth nutes and didn't plan on changing to bloom until week 2 flower is over.

the main question in all of this, will my final yield be effected even though it's still early on in flower and do I keep feeding this reduced ec until they perk up?

Or do I flush?

Or are these basically fcked now and the chance they will recover won't be worth the end result.

So annoyed - 7 weeks down the pan.

If they do come round how long am I waiting?

It's dark green leaves, that are clawing.
Is it possible to survive an N overdose I'm only a few days since 12/12

I'll try to take some pics later

I would post pics ....but to start with if I were you ....let them dry out good between waterings and don't feed for the next few ....sounds like N tox ....but we can only guess with no pics .....GL

I'll post pics in a few hours - assuming I'm correct with this N overdose - what's the repair ?

Just keep feeding at the reduced 0.8ec until they perk up?

Will tne buds at the end be effected because of this - literally under a week since 12/12

What's the prognosis ?

No feed every time - in coco you don't miss a feed - get fed every day same time every day at lights on

I just need to know if it's worth carrying on....

I done same thing on my last grow and got 0.8 grams per watt so much be tne strain ...

Typical

You shouldn't be feeding every time that's your problem maybe it worked ok last time but you need to be giving them plain water

But they have been fine for the last 5.5 weeks, I've never heard of skipping a feed in coco

Will they bounce back?

They are showing signs of N overdose with claw like dArk green leaves.

All I really need to know is do plants with N toxicity not long into flower.... perform as well as they could if the problem is resolved and what is the best way to resolve it in coco

I know it's N overdose - and as many people on many forums will tell you - do not miss a feed in coco

I am not sure but It seems like no one else knows either

Thanks for the replies

Re: coco, if you are feeding every watering you should be doing it at half strength.
Otherwise alternate full strength and plain water.

Don't over-react to some clawing.
And some strains are dark green to begin with.
Definitely not anything to cull a crop over.
Ease back on the nutes.
Let dry out fully before next watering.

But definitely post a picture or two for the best advice.

I don't want to Over feed them or keep feeding them. just want know what the best course of action is from now AND how drastically it will effect tne end result.

Is flushing advised in coco
If not is tne 0.8ec I dropped to good enough for now considering I was at 1.4ec

I appreciate everyone's time on commenting and wil post a pic later

Thanks !

Clawing is a symptom, not a condition.
Does not affect your plants. Some strains are more prone to it.
Dark green foliage doesn't always mean N tox.

I am growing in coco/perlite right now.
Using half strength nutes daily.
Occasional plain water.
Occasionally let them go an extra day without anything.
Sometimes you gotta let the pot dry out.
Stresses the plant a little in a good way.

Can't see why flushing would not be beneficial in a nutrient overdose of elements in coco, why not get something simple like NFT? it's almost fool proof.

That depends how you define bounce back it's not a harvest ending problem but you will get smaller weird shaped buds
