overferted, stalled seedlings - dont want to drown roots

[GreenBalls]

Hi folks,

My auto seedlings have stopped growing at about 2" tall, in the middle of pushing out the 4th leaf set. I thought I'd be patient and leave them, but it's been about 5 days now.

I think it's because I accidentally fed them (although it was a very small amount around the pot edge) some strong nutes at about 1.0 e.c. - they are a bit droopy and their leaf tips point to the ground too.

The thing is, being so small in 15l pots of coco, I don't want to flush/cleanse them because I'm wary of over watering and drowning the roots etc which has happened before.

I overferted four seedlings - the cheap white label seed one has basically recovered and is powering ahead now... the three Mephisto ones have completely stalled.

Any advice is appreciated. Thanks

Sorry I was editing for clarity and for some reason it's double posted - hopefully a mod can delete one. Thnx

Picture with lights out would be helpful

And whats your environment like?

[GreenBalls]

The environment has always generally been ok, during last couple of hot days the temp has been at the high end of 30-31c, but the other plants are happy and healthy generally.

Plant one:



Plant two:

looks underfed rather than overfed, you sure the ph is correct?
they are very pale green, you are feeding every time you water?

the one strong feed caused the burnt tips,
but i don't think they are getting enough food in general

[Bomber]

I agree with Monster. They look hungry to me.

[GreenBalls]

I don't know what to say... the yellowing on the one plant began suddenly in the last few days, after the 'down pointing leaves' and droopiness started.

But my other two plants look exactly the same except they aren't yellowing.

Are you recommending that I feed them??

[GreenBalls]

Feeding with every water at the right EC. Always checking pH.

Thought I was doing everything right, they were growing super fast. Then it all stopped and the only thing that changed was that accidental strong feeding

[Bomber]

What’s your base Ec?

Are you water/feeding daily and at what PH?

You will not drown these in coco.

[GreenBalls]

Background ec is 0.4.
As they're so small/young I was feeding around 0.6ec, not too much, every couple of days (as I read that even with coco, you shouldn't do a full water to run off, until they're vegging with good root system).

I've been feeding daily since your suggestion. They are still droopy and growing very slowly, though new growth is green.

Should I continue feeding daily?
And for future reference - are you saying that even if I do one overferting which makes the tips point down, I should still continue feeding normally after that?
